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.

EXPLORE SCIENTIFIC 68° Ar Eyepiece 16mm (1,25")
With the introduction of the 68° Series we are pleased to make two important improvements in eyepiece manufacture, the first being 15 layer Enhanced Multi-layer Deposition (EMD™) coatings on all glass-to-air surfaces to gain maximum contrast, and waterproofing the eyepiece with the use of Argon gas purging instead of standard Nitrogen gas. Although Nitrogen is a fine choice that will last for many years, Argon is a larger molecule that maintains its protective properties over a wider range of temperatures, and is even more resistant to diffusion thereby further extending the protective waterproof environment of the eyepiece body. Through computer-optimized design, a careful selection of optical glasses, and enhanced multi-layer deposition coatings, the Explore Scientific 68° Series™ eyepieces produce long eye-relief and ensure high image-correction, a flat field, and high contrast across the entire image field. An excellent choice for those who make extended visual studies of detail with subtle variations of brightness, and for those who must wear glasses while observing. All 68° Series eyepieces are fully EMD (Enhanced Multi-Layer Deposition) coated and edge-blackened to produce superior contrast.

BRESSER Pollux-II 150/1400 EQ3 Reflector Telescope with Smartphone Adapter & Solar Filter
Explore the beauties of the night sky with this complete telescope set. Everything is included so that you can get started immediately with the fascinating hobby of astronomy: the astronomical reflector telescope with 150 mm aperture and 1,400 mm focal length, the equatorial mount, the tripod and extensive accessories for exciting observations. Especially important for beginners: the system is very easy to use. Particularly the Moon, the planets and the Sun appear impressive through the Pollux-II. Powerful performance for your first celestial observations – the telescope Take your first steps in astronomy with this classic reflector telescope of the "Newton" type. Because it is equipped with an additional lens inside the focuser, it belongs to the group of the so-called "catadioptric" optics. One advantage of this combination of lens and mirror: despite the large focal length, the telescope tube is relatively short and therefore easily transportable. In addition, you can look forward to a comfortable observation position at all times. This is because with telescopes of this design you do not look in at the back of the telescope, but at the front and laterally. So you don't have to bend down, even if the reflector telescope is pointed vertically upwards at the sky. The large aperture of 150 mm collects a lot of light from the celestial objects. In addition, 150 mm aperture and 1,400 mm focal length result in a focal ratio (ratio of aperture to focal length) of 1 to 9.3 (F/9.3). This allows you to enjoy viewing your favourite objects at high magnifications with good contrast. Admire especially the planets or details on the Moon through the entry-level telescope. But also some deep sky objects are very nice to observe: open star clusters, globular clusters and bright planetary nebulae such as the Ring Nebula M57 in the constellation Lyra can be seen beautifully through this astronomical telescope. But how close can you get to the celestial eye-catchers? The 150 mm aperture achieves a resolving power that allows magnifications of up to 300x with sharp images. The technical possibilities go far beyond this – theoretically up to 1,050x using the included accessories. However, as the magnification increases, the sharpness of the image can slowly decrease. In addition, high magnification also requires the right environmental conditions. For no matter through which telescope you look, the air turbulence in the atmosphere (seeing conditions) always influences your observation and magnification possibilities. Note for nature lovers: If you choose a Newtonian telescope like the Pollux-II reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed laterally reversed as well as upside down, which makes no difference when observing the sky. However, this type of telescope is less suitable for nature and landscape observation during the day. Would you like to use your new telescope for exciting nature discoveries as well? Then we recommend that you choose one of the BRESSER refractor telescopes. Solid base for gazing skywards – mount and tripod Have you found the perfect location for your journey of discovery into the night sky? Then simply mount your astronomical telescope with the equatorial mount on the height-adjustable aluminium tripod. The special feature of this type of mount: after the so-called "alignment", the positioning of an axis parallel to the Earth's axis, the movement of the celestial bodies only has to be compensated for on this one axis. To do this, you simply point the axis approximately at Polaris. This is a huge advantage over the azimuthal mount, where both axes are moved simultaneously. In addition, the two flexible shafts with fine adjustment make adjusting and tracking the telescope very precise and comfortable. And to ensure that accessories are always at hand, they can be stored on the handy shelf between the tripod legs.Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable! Everything you need, night and day – the accessories The astronomical telescope comes with a wide range of equipment so that you can start admiring the Moon, planets or the Sun straight away. At night, the LED viewfinder helps you keep an overview of the sky. Once installed parallel on the tube and correctly aligned, the small red dot shows you where the telescope is pointing when you look through it. This way, you can align the optics precisely and find celestial bodies more quickly before you then take a closer look with the high magnification. Varying views of the universe: the two eyepieces allow you to marvel at your observation objects in different magnifications. They are simply inserted into the telescope's focuser using their sockets with a standardised 1.25 inch (31.7 mm) diameter. You want to see even more details? Then go for the 3x barlow lens, which triples the magnification of the eyepieces. If you would like to make astronomical discoveries even during the day, use the solar filter to observe the star of our own solar system. It allows you to easily and safely observe sunspots and granulation on the sun. CAUTION: Never point the telescope at the sun without the solar filter! Capture special highlights easily – with the smartphone adapter, you use your smartphone as a camera for your telescope. This way you can quickly take your first photos of the Moon or the Sun, for example, and get started in astrophotography. FEATURES Reflector telescope with 150 mm aperture and 1,400 mm focal length Reflector type catadioptric Well suited for observing the Sun, Moon and planets Height-adjustable tripod with equatorial EQ3 mount Precise adjustment through flexible shafts and fine adjustment in both axes Easy to use, very suitable for beginners Focal ratio F/9.3, therefore good for observing the planets and details on the moon 1.25 inch (31.7 mm) eyepiece focuser Two eyepieces and one barlow lens with 1.25 inch (31.7 mm) extension tubes for different magnifications Safe solar observation with the included solar filter Entry into astrophotography with smartphone camera adapter SCOPE OF DELIVERY Telescope Aluminium tripod Equatorial EQ3 mount Eyepieces: 4 mm and 20 mm (1.25 inch sockets) Barlow lens 3x (1.25 inch socket) LED illuminated dot finder Solar filter Smartphone camera adapter Accessory tray Astronomy software download Instruction manual

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

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. You can use PHD2 Guiding, Guidedog, Metaguide, Guidemaster (freeware) or AstroArt, MaxIm DL (paid).

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“.
