Professional Newton Telescope Complete Set with 200 mm aperture, optimised for photography and with state-of-the-art GoTo mount with Wifi module for control via smartphone and tablet.
- Complete telescope set with all necessary accessories and GoTo function.
- An extremely bright f/4 top-class optics with 200 mm aperture.
- Excellent for photographing large-scale nebulae and galaxies.
- State-of-the-art stable SXD2WL equatorial GoTo mount with Wifi.
- Simple control and GoTo swivelling via smartphone or tablet via Wifi.
- 15 kg photographic carrying capacity allows for loading of much special equipment.
- Comfortable GoTo swivelling by tapping on the display.
- Free STAR BOOK Wireless App with star chart program.
- Free STAR BOOK Wireless App with star chart program.
- Total weight: 27.9 kg.
When you tap 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 controller 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 introduces a new standard of performance and precision in the Vixen mount family.
The cross of axes of the mount has a photographic carrying capacity of 15 kg while weighing only 9.2 kg, making it excellent for mobile observations. Additionally, the motors located in the lower part of the mount also serve as counterweights. This means that the mount requires fewer weights for balance.
Details of the SXD2 Mount
Precision stepper motors and Micro-Step Motion Control System
The heart of the SXD2 is the precision stepper motors, offering better performance and response than previous models. The Micro-Step Motion Control System features powerful yet very quiet drive properties, suitable for both fine movements and rapid swivels.
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 quieter than in previous models.
High-precision worm gears
Advanced manufacturing technologies have eliminated errors in worm gear drives. 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 centre of gravity of the SXD2 right below the intersection 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 degree per turn.
Built-in PFL-II polar finder with lighting
The built-in 5x20 mm polar finder with a 10° field of view has a 3-star alignment system. This eliminates the tedious setting of date and time. The illuminated reticle with variable brightness and automatic shutdown is adjustable in 8 stages and illuminated in red. The alignment accuracy is 3 arc minutes.
Details of the Wireless Module
The Vixen Wifi adapter for EQ mounts enables you to control your Vixen mount via a smartphone or tablet. With the smartphone app STAR BOOK Wireless (free), celestial navigation becomes easy and wireless. Thus, the app instantly turns your mobile device into a controller for the equatorial mount. The response delay of the mount, the biggest disadvantage of wireless connections, has been reduced to a level comparable to wired solutions.
Reduced power consumption compared to traditional controllers with LCD monitor
The power consumption of the mount is reduced by up to 20%, enabling longer observations than with traditional wired controllers such as the STAR BOOK TEN.
Operation similar to the STAR BOOK TEN controller
The STAR BOOK Wireless App is set up similarly to the STAR BOOK TEN controller. Depending on the star chart setting, it contains up to 259,000 celestial objects. Tap on 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 are retained.
Convenient operation
While looking through the telescope, you control the mount by swiping across the star chart in the app. Since there are no buttons, you simply glide your finger across the star chart to comfortably operate the mount.
Comprehensive 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 provides a fairly accurate positioning of the mount. Aligning on three or more stars allows for very precise alignment of the mount for high magnifications. The objects are then precisely and centrally placed 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 next observation with the same settings.
Individual adjustment options
The app offers various individual settings like gear play compensation, red night mode, autoguider, variable GoTo speed, and LED brightness, similar to the STAR BOOK TEN controller. You can also set the timing of the objective tube reversal (Meridian Flip) as desired. 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
