Description

Installing the app for smartphone or tablet enables automatic slewing and tracking as a controller of the SX2 equatorial mount.
Vixen Telescope SX2 Equatorial Mount WL Description
-
Easy control of the equatorial mount with smartphone
It allows you to easily use functions of celestial navigation such as automatic slewing of celestial objects with a smartphone or tablet installing free app STAR BOOK Wireless. Eliminating a need for power consumption by the conventional LCD display, the power consumption on the equatorial mount side is reduced by over 20% consequently supporting a longer astronomical observation and astrophotography.
-
App STAR BOOK Wireless inheriting the DNA of STAR BOOK TEN Controller


If you tap the celestial object you want to see on the star chart, it will be automatically slew into the field of view and tracking will start. Following the display of the STAR BOOK TEN controller, which has been highly evaluated for its comfortable operability, even existing STAR BOOK TEN users can use it without any discomfort.

-
Successor of the SX equatorial mount

While inheriting the excellent operability of the SX equatorial mount, it has been renewed with pulser motor of micro-step motion control that is used in the SXD2 series. Increasing the number of bearings from 1 to 5 pieces assures more stable operation.
-
Appropriate placement of weight balance enables weightless operation.
Heavy objects such as motors are placed intensively on the right ascension body, which rotates along the diurnal motion of the starry sky, and has a role as a weight. Depending on weight of optical tube, there may be no need for additional weight.
-
Dovetail structure allows opticcal tube for speedy setup.
The mounting position of the optical tube is designed with the defact standard dovetail created by Vixen. Optical tube can be set up easily without tools. For safety, it is also equipped with a screw that prevents the optical tube from falling off.
-
Retractable counterweight bar convenient for setup and withdrawal of equipment
Stainless steel with excellent corrosion resistance is used for the counterweight bar. Retractable and storable in the equatorial mount body allows speedy setup. You can use the counterweight common to the SX series of 20 mm in diameter.
