The new enhanced handset has an ST4 interface for an Auto-Guider, such as Sky-Watcher’s Synguider. Features selectable SOLAR, LUNAR and SIDEREAL tracking rates, plus additional selectable adjustment rates of 0.5x, 2x and 16x. Also the hand controller has a convenient facility to invert the direction of the UP, DOWN, LEFT, RIGHT handset keys, so you can have the same directions on the handset as you see through your telescope. Designed for use in both north and south hemispheres.
The DC motor drive runs on 4 "D" cell batteries (not included). Motors for both R.A. and DEC axes, motor cables, enhanced hand controller and battery pack are included.
This dual axis motor drive with Sky-Watcher’s new enhanced hand controller is essential in long-exposure astrophotography as well as a useful accessory for visual astronomy. It precisely controls the telescopes’ tracking speed to compensate for the earth's rotation during long exposure of celestial objects.
