The SX2 equatorial mount offers simple and easy operation of your telescope with a newly developed STAR BOOK ONE dual-axis handheld controller. With Vixen's accurate micro-step motion control technology, the SX2 mount achieves highly stable and smooth rotations of the pulse motors. The SX2 mount is a good choice for starting the first step to serious celestial observing.

The massive motor units are placed in the lower part of the declination body so that the center of balance of the SX2 shifts below the intersection of the RA and Dec axes. This makes the lower portion of the declination body perform as a counterweight and allow the mount to work with less counterweight.

Durable stainless steel is used for the counterweight bar. It is moved back into the mount body for storage by loosing the bar lock lever. It is convenient for transporting the mount and for easy set up.

The SX2 mount comes with the STAR BOOK ONE controller featuring a variety of functions in a simple design. Designed for ease of use, the lightweight STAR BOOK ONE moves the SX2 mount on the X and Y dual axis (RA and Dec directions). Versatile tracking options are available in addition to sidereal and solar tracking rates. Backlash compensation, autoguider port and built-in red LED light are some of the useful functions of the STAR BOOK ONE.
