Vixen Polarscope PF-L II for AP & SX Mounts
Vixen’s latest design of polar finder, allows a simple, hassle-free method of polar alignment. The Vixen Polarscope PF-L II for AP & SX mounts has a reticule showing the Pole star (Polaris) and two other stars (Delta UMi and 51 Cep) in their precise positions. By turning the Polarscope you can easily match the reticle with the asterism of these stars in the sky and mechanically adjust your mount’s azimuth and altitude axes to align to the true North Pole. You can then adjust the Polar star to a more precise alignment using the reticule’s year marking (which runs from 2015 to 2040, but in practise can be used much longer after this) . Using this alignment process, with visual reference to the actual stars in the sky, a complicated alignment, using date and time to calculate Polaris offset from the pole is unnecessary. For alignment in the Southern Hemisphere you simply use the Trapezium asterism (Sigma, Chi, Tau and Upsilon Octantis) of the constellation Octans and position the reticule with the trapezium stars aligned to their marked positions. The Polarscope has built-in LED illumination, which is dimmable in many stages, and ensures an automatic shut-off after 2 minutes, saving your battery life. The PFL-II also has an improved edge sharpness, when compared with its predecessor. FEATURES Lighting: LED illumination, with automatic shut-off Power supply: 3v button cell Accuracy: ≤ 3 arc minutes Dimensions: 47 x 55 x 127 mm Weight: 155g Compatibility: Vixen AP, SX, AXJ, AXD Mounts SCOPE OF DELIVERY PF-L II Allen key Battery CR2032 3v

Vixen SD81SII Telescope OTA
A new 81 mm apochromatic refractor with high-performance Super ED glass (= SD). The advantage of these SD refractors is their short length and low weight.The FPL53 glass reproduces an extremely clear and sharp image due to an exceptionally high elimination of residual colour errors. The SD glass is designed to bring all rays of violet, red, blue, yellow and green together very precisely on the same plane. Thus, the special lens material reduces chromatic aberration across all colours.The new Vixen SD81SII no longer uses spacer plates, which leads to significantly better image quality, especially with bright stars. This means that there are no more spikes on the stars in photographic images, which were otherwise produced by the spacer plates. You will be thrilled when you look at the moon or the brighter planets and observe the moon craters pin sharp and with an extremely high contrast. Observe the ring planet Saturn or the cloud bands on Jupiter.But of course, brighter deep sky objects such as the Orion Nebula or the Andromeda Galaxy can also be observed impressively.In combination with the new optional SD Reducer HD Kit or SD Flattener HD, this refractor allows illumination with a 44 mm image circle for full-frame SLR cameras.The older ED81SII, ED103S, ED115S refractors were originally designed for the visual observer or the photographer using APS-C cameras. However, the new SD series has been optimised for use with full-frame cameras by inserting new inner baffle rings.The large 60 mm focuser allows heavy cameras to be attached without tilting. The supplied flip mirror allows comfortable observation, even in unfavourable observation situations, and also offers a T2 thread for connecting a DSLR camera.Thus, observing in degree view or at a 90° angle is possible. The carrying handle attached to the tube clamps ensures a secure hold when transporting the telescope.FEATURESObjective Lens: D=81 mm, multi-coated 2-Lens SD Apochromat without spacer plates No more spikes on the stars Focal Length: 625 mm (f7.7) Resolution and visual limit: 1.43 arcseconds; 11.3 Mag Light gathering capacity: 134x unaided eyesDimensions and weight: 90 mm dia x 585 mm, 3.6 kg Finderscope: XY Red Dot Finder II Adapter and connections: Adapter thread 60 mm and 31.7 mm for T2-ringConnection 50.8 mm and 31.7 mm socket with flip-mirror diagonal mirrorPhotography: primary focus and eyepiece projection SCOPE OF DELIVERY Refractor telescope SD81SII Tube rings Flip mirror system Carrying handle Dovetail rail Red dot viewfinder

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

BRESSER Messier MC-90/1250 EQ3 Maksutov-Cassegrain Telescope with Smartphone Adapter & Solar Filter
Taking off to the stars from your own balcony – with this complete astronomy set that is easily done. The compact Maksutov-Cassegrain telescope with 90 mm aperture and 1250 mm focal length fits everywhere. And thanks to the high contrast, you will be amazed by fascinating insights into outer space even while standing in the brightly lit city. Especially the Sun, Moon and planets look great through the high-quality optics of the beginner's telescope. The set includes everything you need for successful sky observation: an astronomical Maksutov-Cassegrain telescope with 90 mm aperture and 1250 mm focal length, an equatorial EQ-3 mount, a tripod and extensive accessories. The system impresses with its simple operation, which makes life easier for astronomy beginners in particular. Thanks to its compact dimensions, the powerful telescope is also ideal as a travel telescope for more experienced stargazers. A great combination – the telescope The decisive advantage of the Maksutov-Cassegrain construction: the powerful optics have a long focal length, but can still be easily transported due to their very compact design. The recipe for success is the combined optics of mirrors and lenses with very good imaging properties. The 90 mm aperture admits a lot of light into the beginner's telescope and thus ensures a good resolution. In addition, 90 mm aperture and 1250 mm focal length result in an extremely large focal ratio (ratio of aperture to focal length) of 1 to 13.9 (F/13.9). The impressive result: a very sharp image with excellent contrast. Moon, Sun and planets – especially the celestial bodies in our immediate vicinity are more than worth a look through the BRESSER Messier MC-90/1250 Maksutov-Cassegrain telescope for beginners. But various deep-sky objects are also a sight to behold: go on a discovery tour through space and marvel at open star clusters, globular clusters and so-called planetary nebulae such as the fascinating Dumbbell Nebula M27. Thanks to the resolution of the 90 mm aperture, you can enjoy really sharp images at magnifications of up to about 180x. The technology allows more, but you have to reckon with blurriness at higher magnifications. In addition to your telescope, the air turbulence in the atmosphere (seeing conditions) also determines how much you can actually magnify. Your astronomy start is on a firm footing – mount and tripod The beginner's telescope comes with a height-adjustable aluminium tripod and an equatorial EQ-3 mount – the perfect basis for your exploration of the universe. The special feature of the equatorial mount: you only need to compensate for the movement of the celestial bodies on one axis instead of two. You simply align this axis parallel to the Earth's axis by pointing it approximately at the polar star – a procedure also known as "alignment". For sensitive and comfortable adjustment and tracking, the mount is also equipped with two flexible shafts with fine adjustment. Always ready to hand for every celestial highlight – to this end, your accessories will find their place on the storage plate 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 for stunning stargazing – the accessories With the complete astronomy set, your observations will be under a lucky star. The LED viewfinder, which is easily mounted parallel to the telescope, allows you to keep an overview of the night sky. For this purpose, a red dot is projected onto a small ground-glass screen inside the viewfinder. This dot appears to be floating in front of the sky when you look through the viewfinder. And it does so exactly where the aperture of the telescope is pointing. Thus, precise alignment and finding celestial objects becomes super simple! The 26 mm Plössl eyepiece shows greatness in every respect: With it, you can enjoy 48x magnification with very good imaging properties on this telescope. Would you like to look even closer? Then extend your set with additional eyepieces. Because the socket diameter of 31.7 mm (1.25 inch) corresponds to an international and manufacturer-independent standard, you have a wide choice. A comfortable view into the beginner's telescope at all times – this is ensured by the built-in 90-degree star diagonal mirror. So you can look in from the side with ease, even if your telescope is pointing vertically upwards into the sky. It's not just the night sky that fascinates astronomers with beautiful views. Set out with the solar filter to explore our nearest star. Sunspots and granulation on the Sun are guaranteed to amaze you. ATTENTION: Never point the telescope at the Sun without the solar filter! What could be better than reliving unforgettable moments? With the smartphone adapter, the beginner's telescope becomes a giant lens for your mobile phone in no time. So you can easily capture and share your favourite moments with the Moon, Sun etc. FEATURES Entry-level Maksutov-Cassegrain telescope with 90 mm aperture and 1250 mm focal length Very good for observing the Sun, Moon and planets Very compact dimensions, thus well suited for the balcony or as a travel telescope Height-adjustable tripod with equatorial EQ3 mount Precise adjustment through flexible shafts and fine adjustment in both axes Easy to use, good for beginners Focal ratio F/13.9, thus very sharp image and excellent contrast 26 mm eyepiece of the "Plössl" type with 31.7 mm (1.25 inch) socket for 48x magnification Safe solar observation with the included solar filter Entry into astrophotography with smartphone camera adapter SCOPE OF DELIVERY Telescope Aluminium tripod Equatorial EQ3 mount Eyepiece: 26 mm Plössl (1.25 inch socket) Built-in star diagonal mirror LED illuminated dot finder Solar filter Smartphone camera adapter Accessory tray Astronomy software download Instruction manual
