iOptron's GoToNova 8406 Hand Controller features an 8-line red back-lit LCD screen, and an internal database of 580,000+ celestial objects with user-defined objects to program yourself. With nine slew speeds from 1x to 4°/sec and automatic tracking capabilities in both the Northern and Southern hemispheres, finding and keeping objects centered in the field of view is easy no matter if you're viewing the fast-moving Moon or much slower deep space subjects.
This hand controller offers full GoTo capabilities with one or two-star alignment systems get you observing faster. You can also use the controller to program out periodic errors (PE) and backlash which are common to all worm gears, but can affect your ability to accurately track objects for long periods of time. The hand controller has updateable firmware through the built-in USB port and has a red LED light on the back so you can consult your log or star chart without affecting your night adjusted vision.
