VC200L optical tube assembly.

The high definition star images to the edge of a wide imaging field is the heart of the optical system and the VC200L offers exceptionally outstanding performance in astrophotography.
-
SX2 equatorial mount.

With Vixen's accurate micro-step motion control technology, the SX2 mount achieves highly stable and smooth rotations of the pulse motors.
-
Retractable counterweight bar.
The counterweight bar can be retracted into the mount body for storage by simply loosening the lock lever. This design makes the mount more compact and convenient for transport and setup. The bar itself is made of durable stainless steel, ensuring long-lasting performance.
-
STAR BOOK ONE dual-axis controller.

Designed with ease of use in mind, the lightweight STAR BOOK ONE controller operates the SX2 mount along both the RA (Right Ascension) and Dec (Declination) axes. In addition to standard sidereal and solar tracking rates, it offers versatile tracking options to suit various observing needs.
Useful features include backlash compensation, an autoguider port, and a built-in LED light for convenient operation in dark environments.
-
STAR BOOK TEN star chart go-to navigation controller is available as optional.
The SX2 mount is compatible with the optional STAR BOOK TEN handheld controller, which features an intuitive star chart-based Go-To system and a high-definition color LCD display. With a built-in database of over 270,000 celestial objects, STAR BOOK TEN makes it easy to locate, identify, and track your target with precision.
