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)

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

Vixen SXD2WL VC200L Telescope Set
SXD2WL VC200L Cassegrain Telescope Complete Set with GoTo Mount, Tripod, and EyepiecesThis high-quality telescope set impresses with its large 200-mm Cassegrain mirror optics optimized for photography with a flattener. The telescope is manufactured in Japan and scores with its excellent workmanship, sharpness, and contrast performance. The advantage of this telescope also lies in its short, open design and its low weight. Thus, the optics cool down faster than a closed system.The VISAC primary mirror (= Vixen Sixth-Order Aspheric Cassegrain) is specially designed for astrophotography and delivers a completely flat and color-true image across the entire field of view. Spherical aberration, coma, and field curvature are absolute foreign concepts for this optic. The reason for this is the three-lens field corrector in front of the convex secondary mirror.Although the telescope is optimized for astrophotography, it can of course also be used for visual observation. A special coating technique (state-of-the-art technology) provides the optimal mirror surface for observing and photographing deep-sky objects. It allows for controlled coating and individually corrects errors on the mirrors. You will be amazed when you observe the moon's surface with its craters or Saturn with its ring system. On Jupiter, on a good night, many smaller details in the cloud bands will be visible, as well as the Great Red Spot on the planet. On moonless nights, you can observe the Andromeda Nebula, Orion Nebula, Eagle Nebula, Lagoon Nebula and many other interesting faint objects. The brighter globular clusters can be easily resolved into individual stars.This telescope set "Made in Japan" simply leaves no wishes unfulfilled. The large 60-mm eyepiece drawtube allows for the attachment of heavy cameras without tilting. In addition, the supplied flip mirror enables comfortable observation even in unfavorable observing situations and also offers a T2 thread for connecting a DSLR camera. Thus, you can observe in straight view or at a 90° angle. The carrying handle attached to the tube clamps ensures safe transport of the telescope. The sturdy metal tripod allows for a vibration-free setup of the telescope and mount even in windy weather.The SXD2WL mount is simply operated via a Wifi module with a smartphone or tablet. For user-friendly control of the mount, the free STAR BOOK Wireless app is available. This allows you to use practical functions of celestial navigation such as automatic GoTo swivelling to specific celestial objects very easily via your smartphone or tablet. As the power consumption of the conventional LCD screen (STAR BOOK TEN) is eliminated, the power consumption of the mount is reduced by up to 20%. This enables astronomical observations and astrophotography over longer periods. By tapping the desired celestial object from a list, it automatically swivels into the telescope's field of view and tracking begins. An existing STAR BOOK TEN control can also be used on this mount without any problems. Equipped with the same precision stepper motors as the flagship model, the AXD mount, the SXD2WL brings a new standard of performance and precision to the Vixen mount family.

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 quietly than in previous models. High-precision worm gears Advanced manufacturing technologies have eliminated errors in worm gears. The edges of both the worms and worm gears are exceptionally smooth, allowing very precise tracking. Declination axis as counterweight The massive motor units are built into the lower part of the declination axis, lowering the center of gravity of the SXD2 just below the intersection point of the RA and DEC axes. This reduces the need for additional counterweights. Latitude adjustment 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 steps; fine adjustment with a tangent screw head, about 0.8 degrees per turn. Built-in PFL-II Polar Finder with Illumination The built-in 5x20 mm polar finder with a 10° field of view features a 3-star alignment system. This eliminates the tedious setting of date and time.
