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. 

M 45

Foto von Jörg Ortmann aus Hamm-Pelkum , 5.12.2016 (M 45 mit der BRESSER EXOS 2 GOTO, 24x300 Sek., ISO 400 , Canon EOS 1000 Da.)

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.

Product information "BRESSER Messier NT-203s/800 EXOS 2 GOTO Telescope"
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 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. Also prepared for use with the HR Coma Corrector (part No. 0510330) which eliminates coma, field-curvature and astigmatism. 

BRESSER EXOS-2 GoTo Equatorial Mount. 

Mount, tripod and hand box with computer. This German mount has tracking motors in both axes that follow celestial objects very precisely. The handbox with GoTo works reliable and controls the mount in every situation. Precise ball bearings in both axes ensures minimal backlash at all nine possible tracking speeds. The battery pack (12 V) is conveniently fastened to the tripod shelf and takes eight size D batteries.
The mount rests on a very tough and rigid stainless steel tripod and can take optical tubes of up to 13 kg. GOTO Stargazing at the push of a button !
The Startracker GoTo System enables beginners to start astronomical observations in just a few minutes, and guides you to objects that are hard to localize through a standard finder scope.Just push the button and the GoTo System will find planets, nebulae or galaxies for you and position your telescope automatically and precise. The GoTo System database includes thousands of astronomical objects. The Messier mount with GoTo System allows you to observe without tedious searching, or image faint objects that are hard to find in a standard finder scope.

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.

EXPLORE SCIENTIFIC HR Coma Corrector
After three years of testing and refining we are extremely proud to present the new Explore Scientific High Resolution (HR) Coma Corrector. This corrector is a class of it´s own - it is fully functional for visual use and expands the focal length by only 6%! The Explore Scientific Coma Correktor is delivered as a complete set together with a rotating helical focuser with laser-etched scale, so you get a full package: corrector, adaptor to T2 (M42x0.75mm), adaptor to M48 (M48x0.75) and the helical focuser for visual fun. This coma corrector really is "high resolution" - it deliveres a visual polystrehl performance of 0,98 at f/4 and 0,96 at f/3! So it can stay in the telescope - and you will not only enjoy a tack-sharp Jupiter, but aslo sharp and defined moons in the future! What this means in terms of performance is shown in the three pictures with the graphs - the sharpness increase in those comparisons with and without corrector are stunning (examples are 400mm f/4, f/3,5 and f/3). Please notice: These graphs are for FLAT FIELD! You will get this performance without refocussing! Diameter of the field is 30mm - it doesn´t make sense to increase this with 2" and fast optical systems. Length of the 2" corrector barrel is approx. 85mm and it can be used with almost all 2" focusers on the market. To use the HR Coma Corrector visually, you need to have at least 32mm spare inward travel at your focuser, while the focus is on the same plane as the focusers end. Photographically there is no problem - the HR Coma Corrector shifts the focus outward by about 35mm, so that you will have no problem in achieving focus, when you are able to focus your camera without the HR Coma Corrector. FEATURESEliminates coma, field-curvature and astigmatism in newtonians Diffraction limited performance on axis and in the field Flattens the field Works for very fast systems down to f/3 Four-lens construction Can be used with almost all 2" focusers on the market SCOPE OF DELIVERY High Resolution (HR) Coma Corrector Adaptor to T2 (M42x0.75mm) Adaptor to M48 (M48x0.75) Helical focuser

EXPLORE SCIENTIFIC 82° Ar Eyepiece 11mm (1,25")
Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

EXPLORE SCIENTIFIC 1.25" CLS Nebula Filter
Besides air turbulence, the brightening of the night sky is the biggest obstacle to observing faint objects beyond the solar system. Street lamps and other artificial lighting mean that the sky in human settlements is no longer really black. This affects the contrast and thus the perception of deep-sky objects. Depending on the type of celestial object, however, part of disturbing artificial light can be filtered out, making it easier to observe fainter targets.The EXPLORE SCIENTIFIC CITY LIGHT SUPRESSION - or CLS - filter uses the fact that the artificial lighting is not evenly distributed over the entire spectrum. These colours - in the case of the EXPLORE SCIENTIFIC CLS nebula filter, above all the typical colours of mercury and high-pressure lamps, used in street lighting - are suppressed, but the emissions of deep-sky objects are allowed through. With a slightly brightened sky, some relatively bright deep-sky objects are practically invisible with a telescope, for example the large galaxy M101. Using this filter makes observation much easier. A must have for any visual amateur astronomer.  The EXPLORE SCIENTIFIC CLS can also be used as a useful photographic filter - helping to improve the quality of your telescopic deep sky photos.The EXPLORE SCIENTIFIC nebula filters are delivered with an individual test report - so you can be sure of receiving high-quality filters.SPECIFICATIONS:eliminates disturbing light - e.g. from street lightingenables observation of faint deep sky objectsWHAT'S INCLUDED:1x CLS filter

EXPLORE SCIENTIFIC 1.25" H-Beta Nebula Filter
One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects bejond the solar systems enourmously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artifical light. The Explore Scientific H-beta filter uses a characteristic property of the so called emmission nebulae. Those objekcts glow in special colors, the so called emmission lines. Those emmission lines are linked to chemical elements - in this case hydrogen. The Explore Scientific H-beta nebula filter blocks all other colors (and thereby nearly all of the artificial light) and only the emmission line of the hydrogen can pass the filter. The result is astonoishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburbian skies for example the horsehead nebula is almost not visible with a 300mm telescope. By using this filter you can see the nebula and its structures without problems. A must for every visual observer. The Explore Scientific nebula filters come with a individual test certificate - your guarantee to receive a premium filter.
