Product information "Vixen SD115SII Telescope OTA"
The Vixen SD115IIS is a new 115 mm apochromatic refractor with high-performance Super-ED glass (= SD). The advantage of this SD refractor is its short length and low weight. 

The FPL53 glass reproduces an extremely clear and sharp image by an exceptionally high degree of elimination of residual chromatic aberrations. The SD glass is designed to bring all beams of violet, red, blue, yellow and green very precisely together on the same plane. The special lens material, reduces chromatic aberration across all colours.

The new Vixen SD115SII no longer uses spacer plates, which leads to a significantly better image quality, especially with bright stars. In photographic images, no spikes can be seen on the stars, which were otherwise produced by the spacer plates. In addition, you will be thrilled when you look at the moon or the brighter planets and observe the moon craters pin sharp as well as with extremely high contrast. Also look at 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 in impressive detail.

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 format SLR cameras. 

The older ED81SII, ED103S, ED115S refractors were originally developed for visual observers and photographers using APS-C cameras. However, the new SD series is also optimised for use with full-frame cameras through the use of new inner baffle rings. The large 60 mm eyepiece extension also allows heavy cameras to be attached without tilting. Furthermore, the included folding mirror allows comfortable observation even in unfavourable observation situations and additionally offers a T2 thread for connecting a DSLR camera. This allows you to observe in straight line or at a 90° angle. The carrying handle attached to the tube clamps ensures a secure grip when transporting the telescope.

Vixen SXD2WL Equatorial GoTo Mount with Wifi
Vixen has developed a new generation of SX mounts for demanding observers and astrophotographers. The SXD2WL mount is simply operated via a Wifi module with a smartphone or tablet. By controlling the mount with your smartphone using the free STAR BOOK Wireless app, you can easily use sky navigation functions such as automatic GoTo panning of celestial objects via your smartphone or tablet. By eliminating the power consumption of the conventional LCD (STAR BOOK TEN), the power consumption on the mount is reduced by up to 20%, thus enabling longer astronomical observation and astrophotography. When the desired celestial object is selected from a list, it is automatically panned into the telescope's field of view and tracking begins. An existing STAR BOOK TEN controller can also be used on this mount without any problems. Equipped with the same precision stepper motors as the top model, the AXD mount, the SXD2WL brings a new standard of performance and precision to the Vixen mount family. With a photographic load capacity of 15 kg, the axis cross of the mount weighs just 9.2 kg making it ideal for mobile observations. In addition, the motors mounted in the lower part of the mount also serve as a counterweight, so the mount requires fewer weights for balancing. The SXD2 mount in detail Precision stepper motors and micro-step motion control system At the heart of the SXD2 are the precision stepper motors, which offer better performance and response than previous models. The micro-step motion control system offers powerful and yet very smooth drive characteristics, which are given both in fine movements and in fast pans. Built-in bearings The bearings of the RA and DEC axes and the worm shafts have been significantly improved to reduce the load on the motors. As a result, the motors move much more smoothly than in previous models. High-precision worm gears High-precision processing technologies eliminate worm gear errors. The edges of the two worms and worm wheels are particularly smooth, enabling very precise tracking. Declination axis as counterweight The solid motor units are installed in the lower part of the declination axis so that the center of gravity of the SXD2 is below the intersection point of the RA and DEC axes. This means you need fewer additional counterweights. Latitude setting The latitude is adjustable between 0 and 70 degrees (divided into 3 zones and adjustable +/- 15 degrees per zone, for high, medium and low latitudes); latitude scale in 2-degree increments; fine adjustment with a tangent screw head, approx. 0.8 degrees per turn. Built-in PFL-II polar finder with illumination The built-in 5x20mm polar finder with 10° field of view has a 3-star alignment system. This eliminates the inconvenience of setting the date and original time. The illuminated reticle with variable brightness and automatic switch-off is adjustable in 8 levels and illuminated in red. The adjustment accuracy is 3 arc minutes. The wireless module in detail 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 navigate the sky without any cables. The app turns your smartphone or tablet into a control unit for the equatorial mount in no time at all. The response delay of the mount, which is considered the biggest disadvantage of wireless connections, has been reduced to a level comparable to wired connections. 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 controller. The STAR BOOK Wireless app has a similar structure to the STAR BOOK TEN controller. Depending on the star map setting, it contains up to 259,000 celestial objects. 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 retained Convenient operation When looking through the telescope operate the mount by swiping on the app's star chart. As there are no buttons, simply slide your finger over the star chart to operate the mount conveniently. Extensive astronomical data included In addition to data on easily observable celestial bodies such as Messier objects, NGC objects and IC objects, this also includes the sun, moon, planets, comets and dwarf planets. High-precision alignment By aligning the mount to one or two stars, you can already achieve fairly precise positioning. By aligning the mount to three or more stars, you can achieve high-precision alignment of the mount for high magnifications. The objects are then approached precisely and centrally in your telescope's field of view. The alignment information is saved and can be retained even when the device is switched off. By leaving the telescope in its current state after completing an observation without moving it, you can start the automatic installation with the same settings for the next observation.  Individual setting options As with the STAR BOOK TEN control unit, 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 reversal of the objective tube (meridian flip) as desired. Even if the object moves to the south during tracking, you can prevent the telescope tube from reversing. Important note: Cannot be used on old SX mounts with the old blue Star Book! Technical information about the Wifi module: CPU with 32-bit CISC processor 120 MHz The unit is connected to the mount via a D-SUB 9PIN connector as with the STAR BOOK TEN. It has a 6-pin 6-wire modular plug for external autoguider operation. Supported operating systems are Android 6 or higher, iOS 9.0 or higher, WLAN standard: IEEE 802.11b/g/n. FEATURESRA sprocket: 180 teeth DEC sprocket: 180 teeth Shaft material and diameter: Carbon steel / Decl. 35 mm, RA 40 mm thickness Polar finder scope: 6x20 mm, PFL-II polar finder Fine height adjustment: 0° to 70°, (fine adjustment +/- 15°, height) Backsight rod: 20 mm diameter Azimuth adjustment: worm fine adjustment Power supply: DC12 V; 0.4~1.7 A Maximum load: 15 kg, photographic, without counterweight Counterweight: 1x 1.9 kg and 1x 3.7 kg Tripod connection: 45 mm spigot Dimensions: 36 cm (H) x 12 cm (W) x 36 cm (L) Weight: 8.8 kg (19.4 lb), without counterweight 32-bit CISC processor 120 MHz Operating system: Android 6 or higher, iOS 9.0 or higher Connection: D-SUB 9PIN connector Autoguider input ST4 Power consumption SXD2WL+Wireless unit: DC12V / 0.3-2.0 A (load 10 kg), 0.4-2.2 A (load 15 kg) SCOPE OF DELIVERYSXD2WL EQ mount Wireless unit 2 counterweights: 1.9 kg and 3.7 kg Mounting tools Pole finder PFL-II Cigarette lighter cable

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 retained. Convenient operation When looking through the telescope operate the mount by swiping on the app's star chart. As there are no buttons, simply slide your finger over the star chart to operate the mount conveniently. Extensive astronomical data included In addition to data on easily observable celestial bodies such as Messier objects, NGC objects and IC objects, this also includes the sun, moon, planets, comets and dwarf planets. High-precision alignment By aligning the mount to one or two stars, you can already achieve fairly precise positioning. By aligning the mount to three or more stars, you can achieve high-precision alignment of the mount for high magnifications. The objects are then approached precisely and centrally in your telescope's field of view. The alignment information is saved and can be retained even when the device is switched off. By leaving the telescope in its current state after completing an observation without moving it, you can start the automatic installation with the same settings for the next observation.  Individual setting options As with the STAR BOOK TEN control unit, 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 reversal of the objective tube (meridian flip) as desired. Even if the object moves to the south during tracking, you can prevent the telescope tube from reversing. Important note: Cannot be used on old SX mounts with the old blue Star Book! Technical information about the Wifi module: CPU with 32-bit CISC processor 120 MHz The unit is connected to the mount via a D-SUB 9PIN connector as with the STAR BOOK TEN. It has a 6-pin 6-wire modular plug for external autoguider operation.

Vixen SG-L02 Headlamp red-light white-light
The perfect LED head torch for nighttime observations! Adjusting your eyes to the dark surroundings is very important when making astronomical observations. In dark areas, it is very difficult to use astronomical equipment without a suitable light. With normal lights, however, the light intensity is more important than protecting your eyes against bright light. Using these lights at night makes your pupils contract, which can make it difficult for your eyes to readjust to the darkness. The SG-L01, our first astronomy LED lamp, featured a built-in red LED that provided a solution to this problem. However, the red light did not offer optimal visibility. On our new astronomy LED light, the SG-L02, the LED lights produce warm light to improve visibility. They also ensure that your eyes stay adapted to the dark. The LEDs do not emit light in the sensitive range of 555 nm. The brightness of the white light can be adjusted between 3 and 42 lumen, while the red light can be adjusted between 0.28 and 7.62 lumen. FEATURES Dimmable red light ensures that your eyes stay adapted to the dark Built-in rechargeable battery, charges via USB Waterproof design LED colour can be switched from red to white 0.28 to 7.62 lumen for red light 3 to 42 lumen for white light Dimensions: 41 mm x 33 mm x 30 mm Weight: 29 g DELIVERY CONTENT SG-L02 head torch Strap (size S) Strap (size L) Pocket clip Cable for charging the battery (USB-A plug to USB Micro-B plug)

EXPLORE SCIENTIFIC 1.25" UHC 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 beyond the solar systems enormously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artificial light. The EXPLORE SCIENTIFIC UHC filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colours, their emission lines. Those emission lines are linked to chemical elements - in this case hydrogen at 486nm and 656nm, plus oxygen at 496nm and 501nm. The Explore Scientific UHC nebula filter blocks all other colours (and thereby nearly all of the artificial light) and only the emission line of the hydrogen and oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburban skies for example the Owl-nebula M97, the Veil-nebula NGC6992 or even the bright Dumbell-nebula M27 are not clearly visible. By using this filter you can see the nebulae and their structures without problems. A must for every visual observer.
