This high-quality telescope set impresses with its large 200 mm Cassegrain mirror optics with flattner optimized for photography. The telescope is manufactured in Japan and scores with its excellent workmanship, sharpness and contrast performance. The advantage of this telescope is its short, open design and its low weight. This means the optics cool down more quickly than a closed system.

The VISAC primary mirror (= Vixen Sixth-Order Aspheric Cassegrain) is specifically designed for astrophotography and delivers a completely flat and pure-color image across the entire image field. Spherical aberration, coma and field curvature are completely foreign concepts for these optics. 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 technology (state-of-the-art technology) provides the optimal mirror surface for observing and photographing deep sky objects. It enables controlled coating and corrects errors on the mirrors individually. You will be amazed when you use it to observe the lunar surface with its craters or Saturn with its ring system. On a good night on Jupiter, many smaller details in the cloud bands become visible, like the large red spot on the planet. On moonless nights you can observe the Andromeda Nebula, Orion Nebula, Eagle Nebula, Lagoon Nebula and many other interesting fainter objects. The brighter globular clusters can easily be broken down into individual stars.

This telescope set "Made in Japan" simply leaves nothing to be desired. The large 60 mm focuser allows even heavy cameras to be attached without tipping. Furthermore, the included folding mirror allows comfortable observation even in unfavorable observation situations and also offers a T2 thread for connecting a DSLR camera. This means you can observe in degrees or at a 90° angle. The carrying handle attached to the tube clamps ensures a secure hold when transporting the telescope. The sturdy metal tripod allows the telescope and mount to be shot without vibration, even in windy weather. 
 
The SXD2WL mount is simply operated via a WiFi module with a smartphone or tablet. The free STAR BOOK Wireless app is available for user-friendly control of the mount. This allows you to easily use practical celestial navigation functions such as automatic GoTo panning to specific celestial objects via your smartphone or tablet. Since 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 makes astronomical observations and astrophotography possible over longer periods of time.

If you tap on the desired celestial object from a list, it is automatically panned 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 top-of-the-line 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 mount's axes weigh just 9.2 kg and are therefore ideal for mobile observations. In addition, the motors located in the lower part of the mount also serve as a counterweight. This means the mount requires less weight to balance.

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 scores with powerful yet very quiet drive properties, which are present both in fine movements and in fast panning.

The wireless module in detail

The Vixen Wifi adapter for EQ mounts allows you to control your Vixen mount via a smartphone or tablet. This allows you to use the STAR BOOK Wireless smartphone app (free) to carry out celestial navigation without any wiring. The app turns your mobile device 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 solutions.

Reduced power consumption compared to conventional controllers with LCD monitors
The mount's power consumption is reduced by up to 20%, enabling longer observations than with conventional wired controls such as the STAR BOOK TEN.

Operation similar to the STAR BOOK TEN control
The STAR BOOK Wireless app is structured similarly to the one you already know from the STAR BOOK TEN control. Depending on the star map setting, it contains up to 259,000 celestial objects. Tap a celestial object in the object list and start GoTo. The mount now automatically moves to this target and brings it into the field of view of the telescope. All of the popular features of the STAR BOOK TEN are retained.

Convenient operation
When looking through the telescope, you operate the mount by swiping on the app's star map. Since there are no buttons, you simply slide your finger over the star map and can easily operate the mount.

Extensive astronomical data included
In addition to data from easily observable celestial bodies such as Messier objects, NGC objects, IC objects, this also includes the sun, moon, planets, comets and dwarf planets.

High precision alignment
By aligning it with one or two stars, you can get a fairly precise positioning of the mount. By aligning with three or more stars, high-precision alignment of the mount can be achieved for high magnifications. The objects are then approached exactly and centrally in the field of view of your telescope. The orientation information is saved and can be retained even when the device is turned off. By leaving the telescope in its current state without moving it after completing an observation, you can start the automatic installation with the same settings the next time you observe.

Individual setting options
As with the STAR BOOK TEN control, the app offers various individual settings such as gear backlash compensation, night mode in red, autoguider as well as variable GoTo speed and LED brightness. You can also set the timing of the lens barrel reversal (meridian flip) as desired. Even if the object moves south during tracking, you can prevent the telescope tube from reversing.
