iOptron Go2Nova 8408 Hand Controller for CEM25/CEM25EC/CEM25P Mounts


Use the iOptron Go2Nova 8408 Hand Controller to transform your CEM25, CEM25EC, CEM25P, and other compatible mounts into full GoTo observation platforms. Equipped with over 150,000 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 to quickly and precisely move the mount, and four 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.
