Drive in one axis for Pentaflex and Sky-Watcher telescopes with paraxactic assembly EQ-3-2 and Celestron CG4, which compensates for the rotation of the blue sphere in the right-of-way / hour axis ("flying behind the stars", speed 1x rotation speed blue sphere) and allows you to move the telescope in the axis of right ascension with velocities 2x and 8x the speed of rotation of the celestial sphere. Powered by four R20 batteries (D, 1.5V, there is no battery in the set). On one set of batteries you can work for 3-4 observing nights (up to 30-40 hours, depending on the quality of the battery, ambient temperature, telescope rotation speed, balancing, etc.) Includes motor, remote control and battery compartment. 2 years
