Complete Telescope Set SXD2WL AX103S with Wifi-GoTo Mount, Tripod, and Eyepieces This high-quality apochromatic refractor telescope set impresses with its intricate 103mm Triplet ED lens construction. The telescope is made in Japan and stands out for its excellent workmanship, sharpness, and contrast performance. The advantage of this APO refractor lies in its short build length and the completely corrected, edge-sharp optics. The AX103S is a top-class ED apochromat in the refractor range. It offers a Triplet ED lens and, in the rear area, a field flattener lens. The f8.0 refractor is equipped with a central ED lens in the objective and reduces chromatic aberration to an absolute minimum. An optional focal reducer can decrease the aperture ratio to 1:5.6 to achieve quicker results in astrophotography. The Vixen telescope belongs to the new Generation II with improved temperature-resistant lens cell. The integrated field flattener lens ensures a sharp image right to the edge of the field of view, which is very important in astrophotography. The AX103S is specifically developed for photographic purposes, but also visually a real highlight, especially for observing the moon and planets. You will be thrilled when you observe the moon's surface with its craters or Saturn with its ring system. On Jupiter, on a good night, the two bright cloud bands and many smaller details 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 objects. But even weaker celestial objects become visible with this large aperture under a good sky. This telescope set “Made in Japan” simply leaves no wishes unfulfilled. The AX103S is corrected up to full-frame photography and delivers razor-sharp images right into the corners of the image field. The large 60mm eyepiece drawtube also allows for attaching heavy cameras without tilting. Furthermore, the supplied flip mirror enables comfortable observing even in challenging viewing situations and additionally 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 a safe transport of the telescope. The dew cap can be retracted for transport or storage. The sturdy metal tripod allows for vibration-free mounting 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 features of celestial navigation such as automatic GoTo slewing 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%. Thus, astronomical observations and astrophotography are possible over longer periods. By tapping the desired celestial object from a list, it is automatically slewed 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 into the Vixen mount family. The axis cross of the mount has a photographic carrying capacity of 15 kg for only 9.2 kg and is thus excellently suited for mobile observations. In addition, the motors located in the lower part of the mount also serve as a counterweight. This means the mount needs fewer weights for balancing. The SXD2 Mount in Detail Precision stepper motors and Micro-Step Motion Control System 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 is characterised by powerful yet very quiet drive properties, both in fine movements and in fast slews. 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. This allows the motors to move much more quietly than in previous models. High-precision worm gears High-precision manufacturing technologies eliminate errors in the worm gears. The edges of both worms and worm gears are particularly smooth, allowing for very precise tracking. Declination axis as counterweight The massive motor units are built into the lower part of the declination axis, so that the centre of gravity of the SXD2 is below the intersection point of the RA and DEC axes. This means you need fewer 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, approx. 0.8 degrees per rotation. Built-in PFL-II polar finder with illumination The built-in 5x20mm polar finder with 10° field of view features a 3-star alignment system. This eliminates the need to set date and time. The illuminated reticle with variable brightness and automatic shutdown is adjustable in 8 stages 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), you can perform celestial navigation without any wiring. Thus, the app instantly transforms your mobile device into a control for the equatorial mount. The response delay of the mount, considered the biggest disadvantage of wireless connections, has been reduced to a level comparable to wired solutions. Reduced power consumption compared to conventional controls with LCD monitor The power consumption of the mount is reduced by up to 20% and thus allows longer observations than with conventional wired controls like the STAR BOOK TEN. Operation similar to STAR BOOK TEN control The STAR BOOK Wireless app is designed similarly to what you already know from the STAR BOOK TEN control. It contains up to 259,000 celestial objects depending on the star chart settings. Tap a celestial object in the object list and start the GoTo. The mount now automatically moves to this target and brings it into the field of view of the telescope. All popular features of the STAR BOOK TEN remain available. Convenient operation While looking through the telescope, you control the mount by swiping on the star chart of the app. Since there are no buttons, you simply slide your finger over the star chart, allowing you to conveniently operate the mount. Extensive astronomical data included This 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 Alignment on one or two stars already gives you quite an accurate positioning of the mount. By aligning with three or more stars, a very precise alignment of the mount for high magnifications can be carried out. The objects are then positioned exactly and centrally in the field of view of your telescope. The alignment information is saved and can also be retained when the device is turned off. By leaving the telescope in its current state after an observation, without moving it, you can start the automatic installation with the same settings during the next observation. Individual Adjustment Options The app offers various individual settings such as gear backlash compensation, red night mode, autoguider, variable GoTo speed, and LED brightness, just like the STAR BOOK TEN control. You can also set the timing of the objective tube reversal (Meridian Flip) according to your wishes. Even if the object moves south during tracking, you can prevent the telescope tube from reversing. Important Information Not usable on old SX mounts with the old blue Star Book Technical Information on the Wifi Module CPU with 32-bit CISC processor 120 MHz The unit is connected to the mount with a D-SUB 9PIN connector as with the STAR BOOK TEN. It has a 6-pin 6-wire modular connector for external autoguider operation.

The SLV eyepieces with high-quality lanthanum glass provide remarkably clear and high-contrast images of the night sky right to the edge of the field of view. The lanthanum elements almost completely eliminate chromatic aberration, producing a colour-neutral image right up to the edges. The lenses are also fully multi-coated for high light transmission. The eyecup can be twisted up and down, making the eyepiece suitable for glasses wearers. The large exit pupil distance of 20 mm means that the eye does not become fatigued during longer periods of use, and the entire field of view can be seen clearly even when wearing glasses. The eyepiece also features a standard 1.25" filter thread for colour and nebula filters. In addition, the insides of the eyepiece sleeves are fully blackened to reduce distracting reflections.
