With improved tracking accuracy thanks to its new low periodic error of less than ±10 arcsec, and larger gear switches on both axes to make access and adjustments easier the iOptron CEM25P Equatorial GoTo Mount makes an ideal mount for most astronomy and astrophotography needs.
It includes the motorized mount, the Go2Nova 8408 computer hand controller, a tripod upgrade to a sturdier 2" model, and the AccuAlign illuminated polar scope. Its built-in 32-channel GPS receiver transmits accurate date, location, and time to the hand controller, so when you change your position, the telescope can be set up quickly with accurate information. For precise tracking, as required during long-exposure astrophotography or observation sessions, the CEM25P has the capability for you to program out the Periodic Error Correction (PEC) common to all worm gears. With a maximum payload capacity of up to 27 lb, this mount is ideal for most medium to large refractor, reflector, or catadioptric OTAs with Vixen-style dovetail plates, while still being able to handle imaging rigs.
The stepper motor is controlled by the Go2Nova hand controller. This system has an internal database of 150,000+ celestial objects, multiple alignment assistance procedures, and updateable firmware through the built-in serial port. With nine slew speeds and automatic tracking capabilities, finding and keeping objects centered in the field of view is easy whether you're viewing the fast-moving Moon or much slower deep space subjects.
