Vixen SX2WL A105M II Telescope Set

This high-quality refractor telescope set impresses with its 105 mm achromatic optics. You will be amazed when you use it to observe the surface of the moon with its craters or Saturn with its ring system. The long focal ratio of F9.5 ensures only slight colour shifts and good contrast. The telescope is manufactured in Japan and impresses with its excellent workmanship. The optics are therefore highly recommended for beginners and advanced users who value high quality and do not want plastic in the processing, because the telescope is made entirely of metal. The large focuser, which is also used on the large SD refractors, allows even heavy cameras to be attached without tilting. The supplied flip mirror allows convenient observation even in unfavourable viewing situations and also offers a T2 thread for connecting a DSLR camera. 

You will be amazed at what you can see in the sky with an aperture of 105 mm. For example, you can observe the rings of the planet Saturn wonderfully with it. On a good night, the two bright cloud bands and many smaller details, such as the large red spot on the planet, are also visible on Jupiter. On moonless nights, you can observe the Andromeda Nebula, Orion Nebula, Eagle Nebula, Lagoon Nebula and many other interesting objects. Furthermore, fainter celestial objects also become visible with this aperture. Depending on the darkness of the sky, the globular star cluster M13 can even be resolved into individual stars. The sturdy metal tripod allows the telescope and mount to be mounted without vibration, even in windy weather.

The ultra-modern SX2WL mount is simply operated via a Wi-Fi module with your smartphone or tablet.
By simply controlling the mount with your smartphone or tablet and using the free STAR BOOK Wireless app, you can easily use sky navigation functions such as automatic GoTo panning for many celestial objects. By eliminating the conventional LCD display (STAR BOOK TEN), the power consumption on the mount is reduced by up to 20%, thus enabling longer astronomical observation and astrophotography.
When you touch the desired celestial object on the star chart, it is automatically pointed into the telescope's field of view and tracking begins.

NOTE: An existing STAR BOOK TEN or ONE 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 SX2WL brings a new standard of performance and precision to the Vixen mount family.
With a photographic load capacity of 12 kg, the axis cross of the mount is just 7 kg light, making it ideal for mobile observations. In addition, the motors mounted in the lower part of the mount also serve as a counterweight and the mount therefore requires fewer weights for balancing.

The SX2WL mount in detail

Precision stepper motors and micro-step motion control system
At the heart of the SX2 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 smooth drive characteristics, which are present in both fine movements and 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 running surfaces of the two worms and worm wheels are manufactured to be particularly smooth, enabling very precise tracking.

Declination axis as counterweight
The massive motor units are installed in the lower part of the declination axis so that the center of gravity of the SX2WL 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 in +/- 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.

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 "STAR BOOK Wireless" smartphone app transforms 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 control unit
The STAR BOOK Wireless app has a similar structure to the STAR BOOK TEN control system. 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 of the mount. By aligning 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 the field of view of your telescope. 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 controller, the app offers various individual settings, such as gear backlash compensation, night mode in red,
autoguider, variable GoTo speed and LED brightness. You can also set the timing of the reversal of the objective tube (meridian flip) as required.
Even if the object moves to the south during tracking, you can prevent the telescope tube from reversing.

Important information: Cannot be used on old SX mounts with the old blue star book
