Die BRESSER EXOS 2 Goto Montierung

von Jochen Fehmer


Mein neustes Testobjekt ist die BRESSER EXOS 2 Goto Montierung. Nun ja, in der Astronomie- Szene ist sie nicht gerade als die Montierung schlechthin bekannt und die Meinungen gehen weit auseinander.

Also ab ins Lager und eine BRESSER EXOS 2 Goto auf die Sackkarre und ins Auto damit. Mir fiel auf, die Dimensionen des Kartons sind echt übersichtlich, kein langer schwerer wie ich es von anderen Montierungen gewohnt bin. Es sei gesagt, es war keine überprüfte oder eine ausgesuchte, es war eine von der Stange oder besser gesagt vom Regal.

Zuhause angekommen und gestärkt von einem Abendessen machte ich mich ans Werk.

BRESSER EXOS 2 GOTO mit EXPLORE SCIENTIFIC AR102
BRESSER Montierung EXOS 2 GOTO

Ich packte die Montierung im warmen Wintergarten aus, denn draußen war es schon sehr kalt, minus 4 Grad. Als erstes das Stativ. Es ist aus Stahlrohr, leicht und mit zwei Feststellschrauben pro Fuß…das finde ich schon einmal gut. Trotz des leichten Gewichts scheint es sehr stabil zu sein. Dann kam der Montierungskopf; die Motorenabdeckungen sind aus Kunststoff. Egal, wenigstens sind die Zahnräder und die Kugellager einigermaßen vor Staub und Feuchtigkeit geschützt. Auch da fiel mir auf, dass die Montierung sehr leicht ist. Die Montierung auf das Stativ zu schrauben ist sehr einfach, eine große Drehstange erleichtert das ungemein. Gute Idee,wenn es draußen nicht gerade warm ist. Dann die Gewindestange an die Montierung geschraubt. Ein Gewicht ist im Lieferumfang enthalten, dass auf die Stange geschoben und fest gezogen. Handbox angeschlossen und das DEC. Kabel installiert. Fertig. Die BRESSER EXOS 2 GOTO Montierung macht so einen guten Eindruck, alle Schrauben sind groß genug um auch mit Handschuhen bei niedrigen Temperaturen arbeiten zu können. Allein vom Aussehen gefällt sie mir sehr gut.

Aber, gut aussehen reicht nicht. Leider suchte ich vergeblich nach einer Polsucherbeleuchtung. Diese muss als Zubehör gekauft werden. Dafür bekommt sie keinen Applaus. Es geht zwar auch ohne, aber mit der genauen Einordnung fällt und steht die Beobachtungsnacht. Schade.

Ich habe das mitgelieferte Batteriefach mit Batterien gefüllt. Ich wollte so damit arbeiten wie sie ausgeliefert wird. Ein Netzteil kann man als Zubehör erwerben.

Auf geht’s, Montierung angestellt. Als erstes fiel mir das sehr große Display der Handbox auf. Sehr angenehm die Infos zu lesen. Keine Laufschrift sondern stehende Buchstaben. Die Umstellung auf unsere deutsche Sprache ist kein Problem. Nur dass die Schrift auf einmal viel größer wurde….warum dieses? Keine Ahnung, eventuell sind viele Deutsche kurzsichtig. Die Zeit und das Datum musste ich nicht mehr eingeben, bei Bresser werden die Montierungen mit dem Goto versehen, so dass alles schon eingegeben wurde. Auch hier ist zu beachten wenn es eingegeben werden muss, erst das Jahr, Monat und dann den Tag. Nun zum Standort: Vorgegeben sind etliche Länder und Städte. Da es aber keine Updates mehr gibt kann man eigentlich sofort damit beginnen seinen eigenen Wohnort einzugeben. Dafür einmal nach unten mit den Pfeiltasten.

Die Zahnräder hinter der Abdeckung

Längen,- und Breitengrad eingeben. ( Wenn man den nicht weiß einfach im Internet oder Handy gucken ), Zeitzone hier in Deutschland ist 01. Wenn alles eingegeben ist bestätigen und das ist erledigt. Jedes Mal wenn man nun die Montierung ein schaltet nur noch auf Benutzerstandort gehen und fertig. (interne Batterie). Ich hatte für die erste gemeinsame Nacht mir folgendes vorgenommen.

Doppelschiene und 200 mm Canon Objektiv mit einer Canon EOS 6 D und 8x50 Sucher mit einer ASI ZWO 120 Guiding mit PHD2. Normalerweise sollte man die Montierung in DEC. und RA. auf vorgegebenen Pfeile stellen, dieses wollte ich aber nicht. Ging ja auch nicht, da ich mit einer Doppelschiene arbeiten wollte. Also ausgerichtet und angeschaltet. Ich wollte eine 3 Sterne Ausrichtung machen. Machte ich dann auch, einfach der Sternvorschläge ohne Widerworte folgen. (Wie in einer guten Ehe, keine Widerworte) Drei Sterne durch und fertig. Ich habe keine Ahnung ob das richtig war, schließlich war ich noch im warmen Wintergarten.

Zum Schluss sollte sie auf Home Position fahren, das tat sie auch mit der Querstellung meiner Ausrüstung. Natürlich habe ich vorher das Gewicht der Kamera, Objektiv etc. genau ausgependelt. Das ist sehr wichtig, die Gewichtsverteilung sollte schon passen. Dann ging es raus in die Dunkelheit und in die Kälte.

Die BRESSER EXOS 2 Goto Montierung grob nach Norden ausgerichtet. Nun die Montierung mittels Dosenlibelle auf dem Stativ in Waage gebracht. Dann den Deckel des Polsuchers abgezogen, den Schraubdeckel entfernt. Da keine Polsucherbeleuchtung dabei war habe ich eine Laptop Lampe genommen. Ist eine kleine LED Leuchte mit Klemme und flexiblen Arm…ist zwar kein Rotlicht, geht aber auch. Es geht auch mit der Hand box! In der Hand box vorne ist ein Rotlicht eingebaut mit verschiedenen Helligkeitsstufen. Ohne Probleme reicht die Länge des Kabels aus um in die Öffnung des Polsuchers zu leuchten. Hab ich ausprobiert, klappt. Bei der BRESSER EXOS 2 GOTO ist in der Mitte ein Strich und dort ein Kreis. Da steht Polaris. Es gibt zahlreiche APPs für das Handy. Unter anderem auch die APP- Polarfinder. Diese benutze ich immer. Automatisch habe ich die Position von Polaris. Bitte positionieren Sie den Polarstern auf den Kreis, nicht in dem Kreis. Sie können sicher sein, es passt. Ohne viel Mühe ist das erledigt.

Dann habe ich die Kamera angeschlossen und den Laptop gestartet. Die Scharfstellung ist schon eine heikle Sache. Ich nehme immer den Polarstern. Bis jetzt hat es immer geklappt. Es wäre schade, wenn die ganzen Aufnahmen unscharf oder die Sterne Donuts gleichen, die Zeit sollte man sich nehmen. Zahlt sich später aus.

Die BRESSER EXOS 2 Goto Montierung sollte beim ersten einrichten nur zwei Sterne anfahren, erster Stern war fast in der Mitte des Kameradisplays. Okay, ich gebe zu es war ja das Canon 70-200 mm, F4 Objektiv. Da wäre es sehr traurig wenn ich den nicht gesehen hätte, oder? Beim zweiten Stern viel ich aus den Wolken, die Montierung schlug den Polarstern vor. Alles klar! Doch ich zentrierte unsern Nordstern und bestätigte die Auswahl der Montierung. Da war ich mal gespannt. Ich scrollte auf der Handbox auf den Menüpunkt Messier Objekte und tippte die Zahlen 4 und 5 ein. Die Plejaden sollten es werden, das erste Objekt welches jemals die Montierung angefahren hat…..ein Stück Geschichte. Auf ging’s, sehr langsam und ruhig fuhr die BRESSER EXOS 2 Goto den Himmel ab. Das Motorengeräusch ist ruhig, es wird keinen Ärger mit Nachbarn geben. Und dann war meine Überraschung sehr groß, mittig strahlten die sieben Schwestern im Display der Canon 6D Kamera. Der Adler ist gelandet! Oha, das ist doch mal was, innerliche Freude machte sich breit. Doch wie wird es weitergehen? Also, M 31 die Andromeda Galaxie….ist ja nicht weit weg, 31 in dem Menüpunkt Messier Objekte eingetippt und bestätigt. Und siehe da, M 31 in der Mitte. Dann wurde ich übermütig, Deneb im Sternmenü eingegeben, Mittig. Vega eingegeben, wieder mittig. Warum fragte ich mich, denn innerlich hatte ich mich auf Frust eingestellt. Okay, sie wollte es wissen. Ab zu den Plejaden. Eine Minute Belichtung ohne Guiding. Ergebnis: Punktförmige Sterne. 120 Sekunden eingegeben und Belichtung gestartet.

Kurz in die Küche gegangen und einen Kaffee geholt. Da hatten die Sterne leichte Tropfen. Aber gut. Jetzt wollte ich mal loslegen mit der Fotografie. Ich benutzte ein 9x50 Sucher mit einer ZWO ASI 120. APT auf meinem Laptop unterstützt die Astrofotografie. Im Display von APT stellte ich M 45 nochmal richtig scharf, durch die Zoom Funktion eine tolle Sache.

Leider merkte ich die Himmelqualität lies langsam aber sicher nach. Feuchtigkeit machte sich breit und das Seeing wurde von spitze zu überhaupt nicht mehr spitze! Aber egal, es gab aber noch ein paar Einstellungen die ich machen sollte und zwar die Guiding Geschwindigkeit bei der BRESSER EXOS 2 Goto auf 0,500 ändern. Bei PHD habe ich die Kalibrierungsschritte auf 1000 reduziert. Das waren nur grobe Änderungen, ein Feintuning wird es erst bei den nächsten Tests geben. Nun habe ich die BRESSER EXOS 2 Goto mit meinem Laptop verbunden. Ich habe mir einen passenden Stern ausgesucht und die beiden Sachen sich einrichten lassen. Fertig. Die Ausschläge der Korrektur hielten sich in Grenzen. Also gut, dachte ich und wechselte in mein Belichtungsprogram. Ich stellte ISO 400 ein, 180 Sekunden Belichtungszeit und insgesamt sollten 30 Aufnahmen gemacht werden, also 2 Stunden. Ich startete die Aufnahmen. Ich war gespannt, denn man kann live die Korrekturen des Guiders sehen. 0,30 -0,85, in dem Bereich lagen die Zahlen. Das ist jetzt echt völlig in Ordnung, obwohl ich von anderen Montierungen ganz andere Zahlen gewohnt war.

M31

M31, die Andromeda Galaxie. Aufgenommen mit einer Canon EOS 6 D und der BRESSER EXOS 2 GOTO Montierung. ISO 400/30x120 Sek.

Dann war das erste Foto fertig. Ich vergrößerte es auf dem Laptop, und man staune, die Sterne waren Punkte. Dann wurde es Zeit sich ein wenig aufzuwärmen und ich ging ins Haus. (Rentner Astrofotografie, bin halt über 50!) Nach knapp 2 Stunden ging ich raus in die dunkle, kalte Nacht um die Aufnahmen etc. zu kontrollieren. Alles noch in Ordnung. Die Schuhsohlenwärmer aus dem Baumarkt hielten das Objektiv und den Sucher Tau,- und Eisfrei. Ich entschied mich nun mit dem Sigma 120-400 mm mit F5,6 auf die Andromeda Galaxie zu schwenken. Objektiv gewechselt und dann M 31 eingegeben. Unsere Nachbargalaxie war mittig im Display der Kamera.

Anschlussbox

Die Anschlussbox der BRESSER EXOS 2 GOTO Montierung. Von links nach rechts: ST4 für Auto-Guider zum Nachführen von länger belichteten Aufnahmen, Strom, An,-Ausschalter, Hand box und Stecker für DEC.-Achse.

Das Guiding musste ich neu starten, es wollte mit der alten Einstellung nicht mehr. Das dauerte aber nicht lang und die Belichtungen konnten beginnen. Die Tests mit „richtigen“ Teleskopen werden in den nächsten Wochen folgen. Auch diese Belichtungsreihe klappte auf Anhieb. Um drei Uhr rum war es dann auch gut. Die Batterien waren noch nicht am Ende, ich aber. Alles aus stellen, wegstellen und müde ins Bett fallen.

FAZIT DES ERSTEN TESTS MIT DER BRESSER EXOS 2 GOTO

Im Großen und Ganzen bin ich positiv überrascht. Sie hat Ihre erste Testnacht sehr gut überstanden. Sie hat das gemacht was sie sollte und wofür sie entwickelt, gebaut und verkauft wird. Alleine das Piepsen der Hand box nervt ein wenig. Kann man nicht abschalten, wenn es zu viel wird einfach Gewebeband draufkleben. Mit der Hand box muss ich mich noch ein wenig beschäftigen, wie eigentlich mit der ganzen Montierung. Als ein richtiger Test kann man es und sollte man es noch nicht sehen, 200 mm und 400 mm Objektive ist noch keine richtige Herausforderung. Aber, aufgrund ihres geringen Gewichts ist sie sehr mobil. Sollte sie wirklich das Zeug haben als Fotomontierung? Das werden wir in den nächsten Tests sehen. Alleine vom Preis her ist die BRESSER EXOS 2 Montierung schon einmal ein guter Kandidat. Sie liegt preislich zwischen Reisemontierung ( meistens ohne Goto-Funktion) und mittelschweren Montierungen, die für den mobilen Einsatz sehr schwer und unhandlich sind.

Testbericht zu BRESSER Full HD Deep-Sky Kamera & Guider 1.25

von Reinhard Pankrath: "Mond am Taghimmel für Astro - Fotografie geeignet?"

Gefreut hatte ich mich über längere Wolkenlücken und einen offensichtlich durchsichtigen, also klaren, Himmel. Wenn man am Tag den Mond so schön sehen kann, obwohl die Sonne noch scheint, kann der Himmel nicht trübe sein und ist folglich auch für die Verwendung eines Teleskopes gut!

Was mich dann doch geärgert hat, war die fürchterliche Luftbewegung des doch so erwünscht klaren Himmels! Aber jeder Test wird erst richtig gut und aussagekräftig, desto schwieriger er durchzuführen ist. So auch hier.

Meine Erwartung schien realistisch: Wenn der Himmel zwar klar ist, aber die Sonne noch scheint, habe ich weniger Kontrast. Und das brachte mich auf die Idee, eine bestimmte Zusammenstellung meiner Geräte zu testen. Um es vorweg zu sagen: Das Ergebnis hat meine Erwartungen weit übertroffen! Aber hier der Weg dorthin:

Equipment:

• Die Bresser Exos 2 Goto Montierung

• OMC 140 deluxe Teleskop (140 / 2000), ein Rumak

• Die HD – Kamera von Bresser mit dem der neuesten Entwicklung entsprechenden back illuminated Chip von Sony

Warum so?

Erstens: Die Exos 2 ist stabil und läuft gut, habe ich sowieso für meine Teleskope. Die Alternative wäre ein Fotostativ – also ist die Wahl klar :-)

Zweitens: Das OMC wurde von Harrie Rutten berechnet inklusive des überragenden Blendensystems, das für einen optimalen Kontrast sorgt. Das sollte bei Tageslicht doch besonders geeignet sein! Eine bessere Abstimmung kann ich bei anderen Teleskopen auch nicht erwarten.

Drittens: Die HD-Kamera von Bresser hat diesen modernen Chip. Rauscharm und besonders lichtempfindlich durch die derzeit modernste Technik. Kann man bei Sony nachlesen, warum diese Technik so ist. Sehr aufwändig und deshalb auch teurer als herkömmliche Cmos (außer bei Bresser, da hat mich der Preis gewundert, andere lassen es sich besser bezahlen). Aber eben effektiv. Und die Lichtempfindlichkeit der back illuminated Chips sorgt dafür, dass die Belichtungszeiten besonders kurz gehalten werden können. Gerade bei Luftunruhe wichtig, je kürzer belichtet, desto mehr „friert“ die Luftunruhe beim Einzelbild ein. Also siehe oben. Soll die Kamera mal zeigen, was sie kann.

Jetzt muss ich etwas gestehen: Beim ersten Probieren der Kamera habe ich mich über ein gegenüber anderen Programmen komplizierteres Einstellungsmenü geärgert. Da muss man tatsächlich die Bedienungsanleitung lesen! So was! - Nun, ich sage jetzt: Gut, dass es alle diese Parameter gibt. Ein bisschen lernen hat mir auch nicht geschadet und bei diesem Test hat es sich bewährt. Da kam das zugute, was man alles regeln kann.

Das Bild war trotz des Sonnenlichthimmels NICHT flau! Korrekturen am Histogramm – bitte feinfühlig, zuviel ruiniert das Bild dann doch – an der Zeit und Verstärkung, am Weißabgleich und so weiter... haben die Aufnahme des Videos mit 1000 Bildern verarbeitungswürdig gemacht. Gut, man muss vor der Aufnahme etwas Zeit investieren, um alles den Gegebenheiten anzupassen. Einer Automatik würde ich es aber sowieso nicht überlassen. Bei Aufnahmen möchte ich doch bitte noch selber eingreifen können, um das Optimum heraus zu holen. Bei dem erreichten Kontrast konnte ich dann auch die Schärfeleistung erkennen und entsprechend fokussieren. Und so entstanden dann die Videos, bis die Wolken wieder zu dicht wurden und ich abbauen musste.

Die Bearbeitung, stacken, nachbearbeiten mit verschiedenen Freewareprogrammen, in das Format des Ergebnisses für die Veröffentlichung umwandeln, erfolgte dann wie immer. Und hier das Ergebnis. Kann man erkennen, dass die Sonne geschienen hat, als die Aufnahme entstand?

Mein Fazit: Die Kamera ist sehr gut zu gebrauchen, auch wenn die Bedingungen schwierig sind, alle Achtung.

Ich freue mich, dass ich auch so den Mond fotografieren kann und nicht immer auf die Dunkelheit warten muss. Das erweitert das Zeitfenster für mein Hobby doch sehr. Und jetzt ärgere ich mich nie mehr über viele Parameter zur Einstellung der Aufnahme! :-)

Liebe Grüße und Clear Sky

BRESSER Messier NT203s/800 Optical Tube
NEW – now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation.In the past few years the Bresser Newton telescopes have become the standard workhorse for Deep Sky astrophotography. We now proudly present the second generation of this telescope, the Bresser NT-203s/800 with Hexafoc and a fast parabolic main mirror. The Bresser NT-203s/800 f3.9 will deliver you deeper images due to its - compared to 8" f/5 systems - oversized primary mirror and therefore faster optical system with the same exposure time. The big 85 mm secondary prevents vignetting for optimal illumination The excellent 2.5" Hexafoc focuser also does not cause vignetting due to its large diameter and makes focussing a joy - the smoothness and shifting-free operation sets new standards in this price class. This groundbreaking focuser, tube rings with 44mm universal standard dovetail and camera mounting feature and a high-end finderscope with haircross and laser-engraved scale  leave nothing to desire even for demanding astrophotographers. The NT-203s/800 Hexafoc has a classical tube construction with an aluminium tube. The focuser can be upgraded with a 10:1 reduction (part No. 0625720) without problems. Ready to use with the  HR Coma Corrector (part No. 0510330) which eliminates coma, field-curvature and astigmatism.Please note: Reflector telescopes with optical design Newton are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest BRESSER refractor (lens) telescopes for landscape and nature observing.CHARCTERISTICS Optical design: reflector telescopeMirror diameter: 203 mm / focal length: 800 mm / F/3.9Maximum recommended magnification: 406xTelescope for night and solar observing Very high quality Hexafoc focuser with 2.5" free inner diameter Diffraction limited optics with parabolic main mirror 8x50 straight through viewfinder with reticle Optimized finder socket for comfortable use Cradle rings with handle and integrated piggyback camera holder (1/4 thread) Smartphone adapter for celestial navigation included Dovetail plate with stainless steel rail Can be connected to SLR cameras (optional T2 ring required) 50.8mm (2) to 31.7mm (1.25) adapter with integrated T2 thread (T2-adapter ring for your camera is needed) Aperture 203 mm Focal length 800 mm Focal ratio f/3.9 Backfocus fully inward focused: 100 mm 85 mm secondary mirror for optimal illumination Large knobs for primary and secondary mirror adjustment Tube without accessories: 8.7 kg - Tube with all accessories mounted: 11.5 kgSCOPE OF DELIVERYOptical tube 26 mm Super Plössl eyepiece 31,7 mm (1.25") Integrated 31,7 mm and T2 adapter Prism rail with stainless steel clamping surface Adapter for 50.8 mm (2") eyepieces 8x50 optical viewfinder Rotatable star map Aperture solar filter Tube clamp with handle and camera holder Smartphone adapter for celestial navigation Software Stellarium (via download)

BRESSER Mobile Solar Charger 60 Watt with USB and DC output
Self-sufficient travel with the BRESSER solar charger Whether camping, sailing, trekking or swimming at the nearest lake – anyone who enjoys being outdoors for long periods of time does not want to do without their smartphone, tablet, powerbank, etc. But one question quickly arises: where can I find the nearest power socket? After all, every battery runs out and our practical everyday helpers can't manage without electricity. With the ultra-compact BRESSER solar charger, you simply use the power of the sun to charge your devices. The environmentally friendly solar energy is free of charge – and you remain independent of the power grid! Simply open it up, put it down and immediately produce green solar powerThe handling is very simple: unfold the solar panel and align it as perpendicularly as possible to the sun. Then connect the device to be charged to the solar charger, either with a suitable USB cable (not included) or with the included DC connection cable. The charging process begins immediately. Which devices can the solar panel charge? The solar charger gets all devices with a USB power supply connection or the above-mentioned DC power plug connection up and running again in no time – e.g. smartphones, tablets, power banks, portable playstations, MP4 players, GPS devices and Bluetooth headphones. It is also suitable for charging large power stations such as the BRESSER Power Station 100 Watt (art. no.3810000) and the BRESSER Power Station 500 Watt (art. no. 3810020) as well as power stations from other manufacturers with suitable connection values.Universal charger with flexible connection optionsTwo black USB A sockets for normal charging and another orange USB A socket with QC3.0 standard for fast charging of newer generations of devices are available for powering your devices. An additional universal connection cable with a hollow DC plug 5.5/2.1 mm in diameter and 2.5 metres long, as well as 10 plug adapters (7.9/5.5mm, 7.4/5.0mm, 6.5/4.3mm, 6.3/3.0mm, 5.5/2.5mm, 5.5/1.7mm, 5.5/3.2mm, 4.8/1.7mm, 4.0/1.7mm, 3.5/1.35mm) are included in the scope of delivery. The polarity of the connectors is as follows: Inner contact = positive (+), outer contact = negative (-). How long does it take to charge a battery?Most modern devices with built-in batteries indicate the current charging status of the battery on a display or status LEDs. The charging process is also automatically terminated by the internal charger of the smartphone or tablet, etc., as soon as the battery is full.Nevertheless, it is helpful to know how long a full charge theoretically takes with an empty battery. This is the only way to choose the right solar panel model for the requirements of the devices you want to charge.Here is a short calculation: Divide the capacity of the battery (mAh) by the charging current of the charger (mA) and multiply this by a factor of 75. This then gives you the approximate charging time in minutes that is required to fully charge the battery at 100% sunshine duration.Example 1: A battery with a capacity of 3000mAh (3.0 Ah) and a charging current via 5 volt USB connection of 3400mA (3.4 amps). So 3000 : 3400 x 75 = 66 minutes. Dividing the result by 60 gives the charging time in hours: 1.1 hours.This means that an average smartphone can be fully charged in just about 1.1 hours with a 60-watt solar panel.   Example 2: A large power station battery with a capacity of 13000mAh (13.0 Ah) and a charging current via 18 volts DC plug connection of 3300mA (3.3 amps). So 13000 : 3300 x 75 = 295 minutes. Dividing the result by 60 gives the charging time in hours: 4.9 hours.This means that an average smartphone can be fully charged in just about 5 hours with a 60-watt solar panel.   Carabiner hook for attachment includedIn order to attach the solar panel securely to an object and align it perfectly with the sun, 4 sturdy snap hooks are included in the scope of delivery. Simply connect them to the riveted ring eyelets of the solar panel and use them to hang the solar charger stably, e.g. on a tent loop, a fence or other suitable holding points. Innovative solar cell technology with high efficiency Monocrystalline silicium cells ensure high efficiency and the fastest possible charging of the device batteries. This means maximum electricity yield per solar surface. As a result, you benefit from relatively high charging currents and short charging times with a compact design.Easy transportThanks to the modern and flat design, you can easily fold the individual segments of the solar panel into a small bag and stow it in your luggage while saving space. Always ready for the next spontaneous use.Robust, dust- and water-repellent materials The durable Cordura fabric is extremely tear-resistant but still flexible. It protects the valuable solar panel from damage and provides the necessary stability during use. The solar panel is dust- and water-repellent, it withstands most weather conditions and is your ideal companion for almost all outdoor activities. Nevertheless, the solar panel should not be exposed to direct rain or extreme humidity.IMPORTANT NOTESThe solar panel does not have an integrated charger or charge controller. Therefore, it is not suitable for directly charging loose battery cells or lead batteries. It is only suitable for smartphones, tablets and power banks, for example, because they always have built-in internal chargers.The solar panel does not have its own battery, but serves exclusively as a power source in sunshine for charging electronic devices.When connecting the devices to be charged via the DC bar plug, always ensure the required voltage and correct polarity. Otherwise, damage may occur to the electronics of the solar panel and the devices to be charged.Do not leave the solar panel outdoors at night with high humidity or in the rain. This could damage the internal electronics.

This then gives you the approximate charging time in minutes that is required to fully charge the battery at 100% sunshine duration.Example: A battery with a capacity of 3000mAh (3.0 Ah) and a charging current via 5 volt USB connection of 2400mA (2.4 amps). So 3000 : 2400 x 75 = 94 minutes. Dividing the result by 60 gives the charging time in hours: 1.6 hours.This means that an average smartphone can be fully charged in just about 1.6 hours with a 21-watt solar panel. Carabiner hook for attachment included In order to attach the solar panel securely to an object and align it perfectly with the sun, 4 sturdy snap hooks are included in the scope of delivery. Simply connect them to the riveted ring eyelets of the solar panel and use them to hang the solar charger stably, e.g. on a tent loop, a fence or other suitable holding points. If you attach it to your backpack, you can even use the time during a hike for charging. Innovative solar cell technology with high efficiency Monocrystalline silicium cells ensure high efficiency and the fastest possible charging of the device batteries. This means maximum electricity yield per solar surface. As a result, you benefit from relatively high charging currents and short charging times with a compact design.Easy transportThanks to the modern and flat design, you can easily fold the individual segments of the solar panel into a small bag and stow it in your luggage while saving space. Always ready for the next spontaneous use.Robust, dust- and water-repellent materials The durable Cordura fabric is extremely tear-resistant but still flexible. It protects the valuable solar panel from damage and provides the necessary stability during use. The solar panel is dust- and water-repellent, it withstands most weather conditions and is your ideal companion for almost all outdoor activities. Nevertheless, the solar panel should not be exposed to direct rain or extreme humidity.IMPORTANT NOTESThe solar panel does not have an integrated charger or charge controller. Therefore, it is not suitable for directly charging loose battery cells or lead batteries. It is only suitable for smartphones, tablets and power banks, for example, because they always have built-in internal chargers.The solar panel does not have its own battery, but serves exclusively as a power source in sunshine for charging electronic devices.When connecting the devices to be charged via the DC bar plug, always ensure the required voltage and correct polarity. Otherwise, damage may occur to the electronics of the solar panel and the devices to be charged.Do not leave the solar panel outdoors at night with high humidity or in the rain. This could damage the internal electronics.

BRESSER StarTracker Astronomical Photo Mount PM-100
Do you already own a photo camera and would like to create impressive pictures of the night sky with the help of the long exposure or even make time-lapse pictures with little effort ? The BRESSER StarTracker Astronomical PhotoMount PM-100 is the ideal base. Not only for beginners in astrophotography, this mount is particularly well suited, but also the experts swear by a compact and easy-to-use mount to automatically compensate for the natural rotation of the earth. The built-in tracking motor rotates the saddle-mounted camera precisely against the earth's rotation and thus the stars remain in pinpoint shape even with long exposures. If you already own a sturdy photo tripod with a video tilt head you can use the photo mount's head directly with the 1/4 inch & 3/8 inch photo thread holes. The pole height (latitude) is then adjusted by the video tilt head. The photo-mount with tripod with carry-case and polar wedge are also available as a bundle - Product No.: 4964120 Which cameras are basically suitable for use with the BRESSER photo mount ? All cameras with ¼ inch (6.3mm) tripod connection thread and bulb length" B "for long exposure are suitable. The BRESSER StarTracker Astronomical Photo Mount PM-100 is designed for a camera with lens of max. 2.0 kg total weight to carry and track in polar mode. In Azimut mode also a camera weight up to 5.0kg is possible.  Large aperture, wide-angle lenses are ideal for the beginning, because the requirements for tracking accuracy accumulate with increasing focal length and exposure time. Thus, a shot with wide-angle lens can be exposed for up to several minutes and the stars remain punctiform without problems. For example, with a 200mm telephoto lens the polar alignment of the photo mount must be exactly right. But thanks to the integrated pole finder tunnel, this is done quickly. After setting up the light and compact StarTracker Photo Mount, simply set the approximate latitude (pole height) and aim Polaris through the integrated pole finder tunnel. Then mount the camera with the photo lens using the quick-release plate on the supplied ball head. With the ball head, the camera can be aligned and determined at any time on any section of the sky. As soon as the tracking motor is switched on, long-time exposure can be started immediately. This does not even take 5 minutes ... The tracking is carried out by a precise stepper motor, which can be controlled by an easy digital setup on LCD screen. Low power consumption allows up to 20 hours of operation with just one battery charge or simply use the micro USB port for an unlimited power supply. FEATURES Equatorial StarTracker Photo-Mount Automatic siderial tracking against the Earth rotation  Different tracking speed setting possible Suitable for northern and southern henisphere Time lapse: from 15 minutes to 48 hours Ballhead with quick release saddle plate and 1/4" Photo thread for Kamera mountingPhoto-Mount with 1/4" threaded bolt for ballhead mounting Additional quick release coupling for ball head removal High precision stepper motor with helical gear for accurate tracking Clear LCD screen and easy setup menu Battery operation 4 x AA batteries or mico USB (optional acc.)  Battery life: up to 20 hours Weight Photo-Mont: 0.63kg Load capacity of Photo-Mount: up to 2.0kg/5.0kg (EQ/AZ) Optional Acc: Polar-wedge, Tripod and carry-case, optical pole finder scope with illumination unit SCOPE OF DELIVERY StarTracker astronomical Photo-Mount head Ballhead with quick release saddle plate User manual

With the ultra-compact BRESSER solar charger, you simply use the power of the sun to charge your devices. The environmentally friendly solar energy is free of charge – and you remain independent of the power grid! Simply open it up, put it down and immediately produce green solar powerThe handling is very simple: unfold the solar panel and align it as perpendicularly as possible to the sun. Then connect the device to be charged to the solar charger, either with a suitable USB cable (not included) or with the included DC connection cable. The charging process begins immediately. Which devices can the solar panel charge? The solar charger gets all devices with a USB power supply connection or the above-mentioned DC power plug connection up and running again in no time – e.g. smartphones, tablets, power banks, portable playstations, MP4 players, GPS devices and Bluetooth headphones. It is also suitable for charging large power stations such as the BRESSER Power Station 100 Watt (art. no.3810000) and the BRESSER Power Station 500 Watt (art. no. 3810020) as well as power stations from other manufacturers with suitable connection values.Universal charger with flexible connection optionsThere is one USB-C connection socket and another orange USB-A connection socket with QC3.0 standard for powering your devices and also for fast charging of newer generations of devices. An additional universal connection cable with a hollow DC plug 5.5/2.1 mm in diameter and 2.5 metres long, as well as 3 plug adapters (3.5/1.35 mm, 5.5/2.5 mm, 8.0/5.5/0.8 mm) are included in the scope of delivery. The polarity of the connectors is as follows: Inner contact = positive (+), outer contact = negative (-). How long does it take to charge a battery?Most modern devices with built-in batteries indicate the current charging status of the battery on a display or status LEDs. The charging process is also automatically terminated by the internal charger of the smartphone or tablet, etc., as soon as the battery is full.Nevertheless, it is helpful to know how long a full charge theoretically takes with an empty battery. This is the only way to choose the right solar panel model for the requirements of the devices you want to charge.Here is a short calculation: Divide the capacity of the battery (mAh) by the charging current of the charger (mA) and multiply this by a factor of 75.

Vixen Wifi Adapter for EQ Mounts
The Vixen Wifi adapter for EQ mounts allows you to control your Vixen mount via a smartphone or tablet. With the smartphone app STAR BOOK Wireless (free of charge) you can perform celestial navigation without any wiring. The app turns your smartphone or tablet into a controller for the equatorial mount in no time. The response delay of the mount, which is considered the biggest disadvantage of wireless connections, has been reduced to a level comparable to wired ones. Reduced power consumption compared to conventional controllers with LCD monitor The power consumption of the mount is reduced by up to 20%, allowing longer observations than with conventional wired controllers such as the STAR BOOK TEN. Operation similar to the STAR BOOK TEN controllerThe STAR BOOK Wireless app has a similar structure to the STAR BOOK TEN controller. Tap on a celestial object in the object list and start the GoTo. The mount will now automatically move to this target and bring it into the telescope's field of view. All the popular features of the STAR BOOK TEN are available.Convenient operation When looking through the telescope operate the mount by swiping on the app's star map. Since there are no buttons, simply slide your finger over the star chart for convenient operation of the mount. Extensive astronomical data includedThis includes data on easily observable celestial bodies such as Messier objects, NGC objects, IC objects as well as the Sun, Moon, planets, comets and dwarf planets. High-precision alignment By aligning to one or two stars, you already get a fairly accurate positioning of the mount. By aligning to three or more stars, you can achieve high-precision alignment of the mount for high magnifications. The objects will then be approached precisely and centrally in your telescope's field of view. The alignment information is stored and can be retained even when the telescope is switched off. By leaving the telescope in its current state without moving it after completing an observation, the next time you observe you can start the automatic setup with the same settings for the next observation. Individual setting options As with the STAR BOOK TEN controller, the app offers various individual settings, such as gear backlash compensation, night mode in red, autoguider and variable GoTo speed and LED brightness. You can also set the timing of the lens tube inversion (meridian flip) as desired. Even if the object moves south during tracking, you can prevent the telescope tube from inverting. Important information: Cannot be used on old SX mounts with the old blue Star Book. FEATURES Can be used on: SX2, SXD2, SXD2-PFL, SXP, SXP-PFL, SXP2, AXJ (without encoder), AXD, AX Not compatible with old SX mounts with blue Star Book CPU: 32bit CISC processor 120MH Connector: D-SUB 9-PIN socket Autoguider connector: 6-pin modular connector for SBIG Operation: Android 6, iOS 9.0 or higher Wifi standard: IEEE802.11b/g Data encryption: WPA2-APK Firmware update: via WiFi connection Operating voltage: DC12V 0,1A (max) Power supply: via mount Dimensions: 56 x 36 x 19.5 mm, weight: 60 g SCOPE OF DELIVERY Vixen Wifi adapter

EXPLORE SCIENTIFIC MN-152 David H. Levy Comet Hunter Telescope
Maksutov Newton MN-152 David H. Levy Comet Hunter Telescope Highly corrected optic for wide-field observation and astrophotography. Developed in collaboration with the famous "comet hunter" David H. Levy. The Maksutov-Newton system does have some pros and cons respectively to the classical newtonian design. Apart from the higher price the main disadvantage is the higher weight - the thick corrector lens at the front is the cause for this. The main advantage of the Maksutov-Newton compared to the classical newton is the sharpness of the field of view. Classical newtonian telescopes do show a sharp pinpoint star image only at the middle of the field of view - outside the optical axis they have a dominant abberation, the so called coma. This is inherent in the newtonian design, and therefore valid for all newtonian telescopes of all brands and not caused by manufacturing tolerances. Coma distorts the star image - the pinpoint star shows a tail, just like a small comet. This decreases sharpness and contrast considerably. The Maksutov-Newton shows a much sharper star image - for most applications the coma is not visible. This results in a high contrast image all over the field of view - for visual observations and for astrophotography with DSLRs alike. This makes the Maksutov-Newton a ideal all-purpose telescope, that is able to show a sharp field without the need for additional correctors.

BRESSER Full HD Deep-Sky Camera & Guider 1.25"
BRESSER Full HD Deep Sky Camera with autoguider: a great camera for different types of astrophotography and for autoguiding. Not only suitable for planets, but also for deep-sky objects such as galaxies, nebulae and star clusters. Dedicated ToupSky Astro Imaging software supports video preview, video recording, video processing, image capture and processing, dark field correction and raw data output. Easy to use, but with professional results. One of the main features of the new backlit SONY IMX290 CMOS sensor is its high light sensitivity, which makes it possible to detect deep-sky objects without active cooling. SONY has increased the quantum efficiency at 533 nm wavelength up to 77%, which is much better than other CMOS sensors have been able to achieve in the past. Connect this camera to a guidescope and attach the camera's built-in ST-4 port, directly to your telescope's equatorial mount guide port and autoguide - using many popular audioguiding programs (PHD, Guidedog and more). Autoguiding enables you to take accurate pictures with long exposure times of several minutes. Thanks to the extra light-sensitive camera, you now always have a suitable guide star to hand, even using short exposure times. An ST-4 protocol connection cable is also included. Simple automatic tracking at its best. You can use this camera with all guiding telescopes, or off-axis guiders that accept a 1.25 " tube, 1.25" filter thread (M28.5x0.6) or C-mount adapter thread (1 "x1 /32"). IMPORTANT NOTES: This is not a stand-alone guider camera. You always need a Windows 10/11 computer to take pictures and for autoguiding. The autoguider software is not included. You can use PHD2 Guiding, Guidedog, Metaguide, Guidemaster (freeware) or AstroArt, MaxIm DL (paid).

EXPLORE SCIENTIFIC 10x60 Finder and Guider Scope with Helical Focuser, 1.25inch and T2 connection
Universal 60mm viewfinder and guide telescope with a focal length of 250mmExcellent 10x60 viewfinder telescope with removable eyepiece unit and crosshairs with adjustable red illumination. The larger aperture and focal length, provide an even brighter field of view and more accurate tracking due to the higher resolution. The precise helical focuser and the 1.25 inch /31.7mm plug-in connection, as well as the T2 camera connection thread (M42x0.75mm), allow the autoguiding required for long time exposure to obtain a point-shaped star image. It can also be used as a mini travel telescope.High quality 10x60 viewfinder telescope with adjustable crosshair illuminationImage sharpness and viewing characteristics lift this viewfinder well above the level of the usual 10x60 viewfinder scopes. The visible image is bright and crisply sharp. Furthermore, this viewfinder has a very large field of view (FOV) of 6.0 degrees. This makes finding and adjusting objects much easier. The existing scale markings (pitch=0.85 degree) on the crosshair are a good reference for estimating distances, and the open centre markings also make it easier to centre objects precisely. All lens surfaces are protected against weathering by multi-coating and guarantee a bright viewfinder image due to the high light transmission values. The adjustable red LED illumination unit is powered by two LR41 coin batteries. The main lens and the crosshairs can be focused independently of each other, giving you perfect focus for your eyes.Compact tracking unit for autoguidingOne of the main applications for this telescope is the so-called autoguiding. Here the usually larger photo-taking optics are actively corrected by a smaller guiding telescope with a second tracking camera. This means that the mechanical fluctuations in the tracking accuracy, which are present in all astronomical telescope mounts, are measured by the tracking camera and compensated accordingly. This is necessary in order to obtain a point-shaped star image on the astrophotos during long time exposures and to avoid unwanted star trails. For this purpose, the guiding telescope is inserted into the existing viewfinder shoe of the photo-taking optics and aligned parallel. If the existing viewfinder shoe is not compatible, a suitable viewfinder shoe is also included. With the 1.25 inch / 31,7mm plug connection at the rear end or via T2 thread connection (M42x0,75mm), a tracking camera can be mounted afterwards. This is held securely by a brass ring clamp and 3 clamping screws. Please note the required back focus for your tracking camera. The focal plane (backfocus) is approx. 22mm behind the T2 thread. The sensitive focusing on the guiding star is done by a large knurled wheel of the mechanically precise manufactured helical focuser. For easy reproduction of the point of focus, this has a white millimetre scale from 0 to 28mm, which is attached by laser engraving. After the tracking camera has been connected directly or via computer to the telescope mount and the necessary basic settings have been made, the first astrophotos with long time exposure can be taken.Use as mini travel telescopeThis viewfinder and guide telescope can also be used quite simply as a mini travel telescope. With the optional eyepieces, a magnification of 9x to 50x can be achieved. Nearly all eyepieces with a focal length of 5 to 26mm and 1.25 inch/31.7mm plug connection are suitable. Especially recommended are the EXPLORE SCIENTIFIC eyepieces of the 52 degree (Art. 02195xx) and 62 degree (02196xx) LER series. Note: Only straight view use is possible.Metal viewfinder holder and viewfinder shoeThe mount of this viewfinder and guide telescope is completely made of aluminium and is a stable base. The viewfinder mount is suitable for many common types of telescopes, such as EXPLORE SCIENTIFIC, BRESSER MESSIER etc. If the existing viewfinder shoe is not compatible, a matching viewfinder shoe is also included. This can be attached to the telescopic tube by means of four M5 screws. The bore distances of the viewfinder shoe are 31.7mm on the longitudinal and transverse axis. The six large adjustment screws with non-slip knurling make it easy to align the viewfinder, even with clammy fingers. All adjusting and clamping screws have plastic tips that effectively prevent the viewfinder housing and viewfinder mount from being scratched.FEATURESExcellent 10x60 viewfinder and guiding telescopeCan also be used as mini travel telescopePerfect image sharpness and good viewing comfortFMC Multi-coated lens surfacesLens focal length: 250mmMax. possible camera weight: 550gRemovable eyepiece/cross hair unitCamera connection via 1.25 inch / 31.7mm plug connection or T2 threadT2 thread: M42 x 0,75mmPrecise helical focuser for focusing the visible imageFocuser travel range: 28mmClose focus distance: 3 mLaser engraved millimetre scale from 0 to 28mm on the focuserFocal plane (backfocus) is approx. 22mm behind the T2 threadSeparate focusing of the crosshair at the eyepieceVery large field of view FOV of 6.0 degreesWith adjustable red cross-hair iillumination Scale markings crosshair with 0,85 degree graduationPower supply of illumination unit: coin battery type LR41 (2pcs)Brass ring clamp and 3 clamping screws on the 1.25 inch plug connectionWith optional eyepieces magnifications from 9x to 50x can be achievedSuitable are almost all eyepieces with 1.25 inch/31,7mm shaftMounting of the viewfinder telescope is completely made of aluminiumViewfinder mount with 6 large adjustment screws with knurled head for easy gripFinder shoe suitable for EXPLORE SCIENTIFIC, BRESSER MESSIER etc.Additionally a suitable viewfinder shoe is includedBore distances of the viewfinder shoe are 31.7mm on the longitudinal and transverse axisAdjusting and clamping screws have plastic tipsWHAT'S INCLUDED10x60 viewfinder/guiding telescopeEyepiece unit with crosshairCrosshair illumination unit incl. batteriesViewfinder holder with viewfinder shoeInstruction manual
