Use the iOptron Go2Nova 8409 Hand Controller to transform your CEM26 center-balanced or GEM28 German equatorial mounts into full GoTo observation platforms. Equipped with over 212,000 objects, the controller plugs into the mount's HBX port for seamless interface, functionality, and power. The controller offers multiple alignment procedures for fast setup, nine slew speeds up to 6° per second to quickly and precisely move the mount, and four preset tracking rates, plus the ability to set the rate yourself for custom uses. Beyond its GoTo ability, the Go2Nova can control optional equipment such as electronic focusers, and interface with GPS modules for increased usability.
