BRESSER Barlow Lens 2x 31.8mm/1.25"
With the usage of barlow lenses, you can extend the equivalent focal length of telescopes and hence increase the magnification of your observed targets. Subsequently, you can use lower power eyepieces in Barlows to act as much more powerful eyepieces, but retain the larger ocular size and more comfortable viewing that comes with lower power eyepiece designs.Due to their two lens design, these Barlow lenses provide a brilliant image quality for the whole visual field and are suitable for observations and photography.  The black coloured Barlow element cell in this BRESSER Barlow Lens 2x 31.8mm/1.25," can be unscrewed and has the same thread as 1.25" filters, allowing it to be mounted in 1.25" eyepieces, t-adapters and other accessories, giving you flexibility of use and the ability to vary magnification in different accessories.  For instance, the black Barlow cell screwed into the average length nosepiece of a standard push fit t-adapter will give around 1.6x magnification on an attached DSLR.  This can be very useful when trying to get to photographic focus with some Newtonians and Solar Telescopes, which lack the necessary amount of in focus travel to get a camera to a prime focus position.FEATURESsuitable for observations and photographydoubling of the focal lengthtwo lens designfully multi-coatedWHAT'S INCLUDEDBarlow lens (1pc)

EXPLORE SCIENTIFIC Zero X Field Flattener 2''/M48 for ED80, ED102 and ED127 APO
Field flattener without reduction factor for Explore Scientific ED80 , ED102 and ED127 APO Refractors The imaging plane of many telescopes is not flat but curved. This means that only the area in the centre is perfectly focused - the edge becomes blurred. The human eye can usually compensate for this image property, but a camera shows increasing blurriness towards the edge of the image field. The Explore Scientific Zero X field flattener eliminates the field curvature in many telescopes with a focal length of approx. 480 to 952 mm. The Zero X field flattener was calculated and developed for Explore Scientific ED80, ED102 and ED127 apochromats with focal ratios of F=6.0 and F=7.5. The image sharpness at the edge is dramatically increased. The stars appear round and no longer distorted - a clear benefit for the whole image aesthetics. The Zero X image flattener can be used not only with Explore Scientific Apos, but also with many other Apos. This flattener does not change the focal length of the telescope. Correction for up to full-frame camera sensors (24x36mm) The Explore Scientific Zero X image flattener has been developed due to the rapid development of ever larger camera sensors. With it, there is finally a field flattener available that illuminates and corrects the field of view for full-frame camera sensors up to 24x36 mm. How to use the Zero X field flattener with M48 thread connection This field flattener has a 2 inch (50.8 mm) plug-in connection on the telescope side, with which it is inserted into the telescope instead of an eyepiece or star diagonal mirror. On the camera side, there is a standardised M48 x 0.75 mm connection thread. This M48 connection thread offers a larger free inner diameter than the usual T2 (M42) thread and prevents vignetting when using large camera sensors. With an optionally available and camera-specific adapter ring, a DSLR camera can be connected to it. The working distance is already set at 55 mm. Of course, mirrorless cameras or special astro cameras can also be used with the M48 thread connection. For this, the appropriate M48 spacer sleeves or adapters are additionally required to set the right working distance of 55 mm. This must always be done with every corrector or field flattener so that the best possible field flattening is achieved.Filter thread on telescope side availableThe telescope-side 2.0 inch plug-in sleeve has an M48x0.75 filter thread (internal thread). Individual 2.0 inch colour or nebula filters can be inserted here to increase the contrast of the images.FEATURESField flattener for Explore Scientific ED80, ED102 and ED127 APO telescopesRemoves field curvature from telescopesProduces round stars even at the edge of the image fieldImage sharpness at the edge is drastically increasedA clear benefit for the whole image aestheticsCorrection of field curvature for up to full-frame camera sensors (24x36 mm)Image field flattener without reduction factorOn the telescope side with 2 inch (50.8 mm) plug-in connection and M48x0.75mm filter threadCamera side with large M48 threaded connectorWorking distance of 55 mm between field flattener and camera sensorFor telescopes with a focal length of approx. 480 to 952 mmOptimised for telescopes with focal ratios from F=6.0 to F=7.5Can also be used for various other APOsFully multi-coating on all lens surfacesHousing made of lightweight aluminium, black anodisedAluminium dust cap for M48 threadSCOPE OF DELIVERYZero X field flattener (1 piece)Dust caps

EXPLORE SCIENTIFIC MPCC Field Flatt. ED APO+Canon EOS T2
The image plane of many telescopes is not plane, but curved. This results in a picture that has its optimal focus only in the center of the field of view - the edge of the field is out of focus and thus unsharp. The human eye is able to accomodate most of this but a camera will show stars that get increasingly unsharp towards the edge of the field. The Explore Scientific Multi Purpose Curvature Corrector eliminates field curvature in a variety of telescopes - Explore Scientific Apos and many other refractors and cassegrain telescopes. This increases the edge sharpness in the image drastically. Improves edge sharpness not only with Explore Scientific Apos, but also with many other refractor and cassegrain telescopes. This image field leveller fits all Canon EOS cameras, but can also be used for other camera types due to the universal T2 thread connection. This requires an optional camera-specific T2 ring. SPECIFICATIONSImage flattener for Canon EOS cameras Eliminates the field curvature of ED APO telescopes Can also be used for various cassegrains The image sharpness at the edge is drastically increased 2 inch/50.8mm push-in connector with filter thread T2 threaded connection (M42x0,75mm) Full multi-coating on all lens surfaces Stainless steel housingAdapter for Canon EOS bayonet included DELIVERY SCOPE Bildfeldebner Canon EOS (1 piece)

EXPLORE SCIENTIFIC 3" 0.7x Reducer/corrector
The EXPLORE SCIENTIFIC 3" 0.7x Reducer/corrector, reduces a compatible telescope's focal length by a factor of 0.7x (for around f/8) and 0.8x (for around f/10) respectively. The reducer/corrector not only reduces the focal length but also flattens the field. Although originally developed for the Explore Scientific ED-APOs 127mm and 152mm, the reducer can be used with many systems - for example with the Explore Scientific ED-APOs 102mm and 165mm (please note, this will not work on the Explore Scientific 80mm ED Apo refractors though). With certain telescope focal lengths, a slight restriction of the correction at the edge of the image field can be expected when using full-frame sensors. This unit comes with 3" barrel adaptor for direct focuser thread M54x0.75 (the standard focuser thread of the Explore Scientific Essential series of ED Apos) and T2 camera adaptor. This reducer/corrector features a free aperture of 65mm, so that it can be used even with cameras that have a large sensor - if the telescope allows for this. Note: As previously mentioned, this Reducer/corrector comes with a screw on ring, which fits the standard focuser thread of the Explore Scientific Essential series of ED Apos. For telescopes which are equipped with the 2.5" HEX Focuser, the optional screw-on adapter part no: 0510366 is needed. Other telescopes, not in the Explore Scientific range, with standard 2" push-fit focusers will need the Explore Scientific 2" Adaptor for 3" Corrector - part no: 0510364 to get this reducer correctly fitted.

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.

BRESSER HD Moon & Planetary Camera & Guider 1.25"
Enter the world of astrophotography now. With the new BRESSER HD moon and planet camera with ST4 autoguider function. This camera is very good for astrophotography with short exposure times, i.e. for celestial objects like the moon, planets or star clusters. For astrophotography with long exposure times for low light deep sky objects, like galaxies and gas nebulae, we recommend the BRESSER Full HD Deep-Sky Camera (Art. No. 4959050) instead, with it's even higher resolution and sensor sensitivity. Equipped with the new high-sensitivity SONY IMX225 CMOS colour sensor, the BRESSER HD moon and planet camera delivers amazing image results with very short exposure times, even with simple telescope equipment. In addition, this ultra-modern camera can also be used as an autoguider, e.g. to actively track the main imaging device with SLR or CCD astro camera. A universal CMOS colour camera that delivers super-sharp lunar and planetary images in particular. The particularly low noise level of this new chip generation from SONY, ensures an exceptionally high brilliance and no cooling is required. Due to the high native pixel resolution of 1280x980, together with suitable telescopes, very beautiful images of the moon, but also detailed planetary images are possible. The ToupSky pro software included in the scope of delivery not only offers the necessary basic functions for image and video recording, but also many helpful special functions for image post-processing and for setting up the Guider. Functions such as live image display, exposure settings, white balance, dark image capture, stacking, timelapse recordings and much more can be individually configured. Especially the very sophisticated software makes it really easy for you to get started in astrophotography. With the automatic settings, you can produce absolutely presentable results without much prior knowledge. If you wish, simply switch off the automatic settings and gradually venture into the individual professional settings. Connect the camera directly to the ST4 connector of your telescope mount and you have fully automatic tracking control. This makes long exposures of several minutes possible without the stars producing unwanted line marks due to the ever-present synchronisation fluctuations of a telescope mount. A corresponding ST-4 connection cable is even included with the camera. Due to the high light sensitivity of the camera, you will always find a suitable guide star even with very short exposure times. For connection to guide tubes or off-axis guiders, the camera has a 1.25" plug-in sleeve, 1.25" filter thread (M28.5x0.6) and C-mount 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.

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. The BRESSER NANO NT-114/500 telescope is the perfect combination of a large Newtonian mirror with a short focal length. The advanced observer who has discovered that light gathering is a more important factor than magnification, will especially appreciate the large 114 mm mirror. Enough light can be reflected into the eyepiece to be able to see even the most distant objects in our solar system at great detail. Suitable also for traveling and to observe large open star clusterns and the milky way. The telescope arrives with a wide array of accessories and almost pre-assembled - observation can start immediately. The BRESSER NANO is a light-to-medium-duty alt-azimuth mount with tripod designed to quickly and easily accept small to medium sized refractors, such as the AR-90s, AR-102s, AR-102xs and the ED-80 APO. Lightweight, fast Newtonians will also match up nicely with the BRESSER NANO AZ mount. As long as your telescope does not exceed 8 pounds and has a Vixen-Style Universal Dovetail bar for mounting the telescope to the mount head, you are good to go. The stainless steel tripod that comes standard with the BRESSER NANO AZ mount has adjustable legs and a wide foot print, which makes the tripod more stable. Spreader vanes with an acessory tray locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum. Do you want to capture what you see ? With the included smartphone holder bracket you can use your smartphone to easily take colour pictures of celestial objects - like through a telephoto lens ! With the included camera adapter ring T2 you can also attach your DSLR or CCD camera direct to the focuser in order to capture high resolution pictures of the Moon by using short exposure times.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.

Thus, the wavelengths of invisible light in the ultraviolet and infrared are also captured. This leads inevitably to a small additional and of course unwanted blur. The solution is this UV + IR Cut Filter, which allows only light in the visible range 400 nm to 680 nm to pass through and blocks all other wavelengths of light. As soon as these disturbing light waves are cut off, the sharpness of the image and the contrast are increased. Suddenly, details on the surface of Jupiter, for example, can be seen that were previously only barely visible. A clear plus, which can be achieved by this filter.Suitable for BRESSER CMOS cameras and other manufacturers with female camera thread M30 x 0.75 mmAfter removing the original screw adapter with sensor protection glass, the BRESSER UV + IR Cut filter is mounted to the camera instead. This filter has a fine M30 x 0.75 mm external thread for mounting on the camera. The exchange is therefore quick and easy. On the opposite side, i.e. on the telescope side, there is a standard C-mount female thread for mounting other accessories. Note: This filter does not have a standard 1.25 inch (31.7 mm) filter thread.

BRESSER Pollux-II 150/1400 EQ3 Reflector Telescope with Smartphone Adapter & Solar Filter (Refurbished)
Erkunden Sie die Schönheiten des Nachthimmels mit diesem kompletten Teleskop-Set auf eigene Faust. So ist für den einfachen Einstieg in das faszinierende Hobby Astronomie bereits alles enthalten: das astronomische Spiegelteleskop mit 150-mm-Öffnung und 1.400-mm-Brennweite, die äquatoriale Montierung, das Stativ und umfangreiches Zubehör für spannende Beobachtungen. Besonders wichtig für den Anfang: Das System ist sehr einfach zu bedienen. Vor allem der Mond, die Planeten und die Sonne geben durch das Pollux-II ein beeindruckendes Bild ab. Starke Leistung für erste Himmelsbeobachtungen – das Teleskop Gehen Sie Ihre ersten Schritte in der Astronomie mit diesem klassischen Spiegelteleskop der Bauart „Newton“. Weil sie zusätzlich mit einer Linse im Okularauszug ausgestattet wurde, handelt es sich um eine sogenannte „katadioptrische“ Optik. Ein Vorteil dieser Kombination aus Linse und Spiegel: Trotz großer Brennweite ist der Teleskop-Tubus relativ kurz und damit transportabel. Außerdem können Sie sich auf eine stets komfortable Beobachtungsposition freuen. Denn bei Teleskopen dieser Bauart schaut man nicht hinten am Ende hinein, sondern vorne an der Seite. So müssen Sie sich nicht bücken, selbst wenn das Spiegelteleskop senkrecht nach oben in den Himmel gerichtet ist. Die große Öffnung von 150 mm sammelt sehr viel Licht von den Himmelsobjekten. Zudem ergeben 150 mm Öffnung und 1.400 mm Brennweite ein Öffnungsverhältnis (Verhältnis der Öffnung zur Brennweite) von 1 zu 9,3 (F/9,3). Dadurch genießen Sie den Anblick Ihrer Lieblingsobjekte in hohen Vergrößerungen bei gutem Kontrast. Bewundern Sie durch das Einsteigerteleskop vor allem die Planeten oder Details auf dem Mond. Aber auch einige Deep-Sky-Objekte sind mit diesem Teleskop sehr schön zu beobachten: Offene Sternhaufen, Kugelsternhaufen und helle planetarische Nebel wie der Ringnebel M57 im Sternbild Leier können sich durch das astronomische Fernrohr buchstäblich sehen lassen. Doch wie nah kommen Sie mit dem Teleskop an die himmlischen Hingucker heran? Durch die Öffnung von 150 mm wird ein Auflösungsvermögen erreicht, das Vergrößerungen bis etwa 300-fach mit scharfen Bildern erlaubt. Die technischen Möglichkeiten gehen zwar weit darüber hinaus – mit dem enthaltenen Zubehör theoretisch bis zu 1.050-fach. Allerdings kann dann mit steigender Vergrößerung die Bildschärfe langsam abnehmen. Außerdem braucht eine hohe Vergrößerung auch die richtigen Umgebungsbedingungen. Denn egal durch welches Teleskop Sie schauen, die Luftunruhe in der Atmosphäre (Seeing-Bedingungen) beeinflusst stets Ihre Beobachtungs- und Vergrößerungsmöglichkeiten. Hinweis für Naturliebhaber: Wenn Sie sich für ein Newton-Teleskop wie das Pollux-II Spiegelteleskop entscheiden, können Sie sich auf einen Spezialisten für astronomische Beobachtung freuen. Das Bild wird allerdings stets seitenverkehrt sowie auf dem Kopf stehend abgebildet, was bei Himmelsbeobachtungen keinen Unterschied macht. Für Natur- und Landschaftsbeobachtungen am Tage ist diese Bauart deshalb allerdings weniger geeignet. Sie möchten Ihr neues Teleskop auch für spannende Naturentdeckungen nutzen? Dann empfehlen wir, dass Sie sich eins der BRESSER Linsenteleskope aussuchen. Stabile Basis für den Blick nach oben – Montierung und Stativ Für Ihre Entdeckungsreise am Nachthimmel ist der perfekte Standort gefunden? Dann montieren Sie Ihr astronomisches Fernrohr dort einfach mit der äquatoriale Montierung an dem höhenverstellbaren Aluminium-Stativ. Der Clou an diesem Montierungstyp: Nach der sogenannten „Einnordung“, der Ausrichtung einer Achse parallel zur Erdachse, muss die Bewegung der Himmelskörper nur noch an dieser einen Achse ausgeglichen werden. Dazu richten Sie die Achse einfach ungefähr auf den Polarstern. Ein Riesenvorteil gegenüber der azimutalen Montierung, bei der beide Achsen gleichzeitig bewegt werden. Über die zwei biegsamen Wellen mit Feintrieb gelingen die Einstellung und Nachführung des Teleskops zudem sehr feinfühlig und komfortabel. Und damit das Zubehör stets zur Hand ist, findet es auf der praktischen Ablageplatte zwischen den Stativbeinen seinen Platz. Alles dabei für Nacht und Tag – das Zubehör Das astronomische Fernrohr kommt mit einer umfangreichen Ausstattung, sodass Sie direkt mit dem Mond-, Planeten- oder Sonnebewundern starten können. In der Nacht behalten Sie durch den LED-Sucher den Überblick am Himmel. Denn einmal parallel auf dem Tubus installiert und richtig ausgerichtet, zeigt Ihnen der kleine rote Punkt beim Hindurchsehen, wo das Teleskop hinzeigt. So richten Sie die Optik durch den Peilsucher präzise aus und finden Himmelskörper schneller, bevor Sie dann mit der hohen Vergrößerung genauer hinschauen. Wechselnder Blick ins Weltall: Durch die beiden Okulare bestaunen Sie Ihre Beobachtungsobjekte in unterschiedlichen Vergrößerungen. Sie werden einfach an ihren Steckhülsen mit standardisiertem 31,7-mm-Durchmesser (1,25 Zoll) in den Okularauszug des Teleskops eingesteckt. Sie möchten noch mehr Details sehen? Dann greifen Sie zur 3-fach-Barlow-Linse, die die Vergrößerung der Okulare noch verdreifacht. Wer auch am Tag astronomische Entdeckungen machen möchte, beobachtet mit dem Sonnenfilter den Star unseres Sonnensystems. Nehmen Sie damit Sonnenflecken sowie Granulation auf der Sonne ganz einfach und sicher in den Blick. ACHTUNG: Niemals ohne den Sonnenfilter das Teleskop auf die Sonne ausrichten! Besondere Highlights ganz einfach festhalten – mit dem Smartphone-Adapter können Sie Ihr Smartphone als Kamera am Teleskop verwenden. So haben Sie schnell Ihre ersten Fotos beispielsweise vom Mond oder der Sonne im Kasten und den Einstieg in die Astrofotografie geschafft. Noch gar keine Erfahrungen mit astronomischen Teleskopen? Dann empfehlen wir für einen leichteren Start in das Hobby Astronomie das zusätzlich erhältliche Buch „Fernrohr-Führerschein“.

NATIONAL GEOGRAPHIC 114/900 Reflector Telescope AZ
This reflecting telescope shows not only the big planets, but also bright deep-sky objects when you are observing under dark skies. Fully equipped, and with a mount that is easy to use, this telescope is ideal for a beginner that has no astronomical knowledge, but wants to immerse him or herself in space. Explore the moons and cloud bands of Jupiter or the majestic rings of Saturn, or find other galaxies, star clusters and nebula on a moonless night. 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 refractor (lens) telescopes for landscape and nature observing.
