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.

Mount
  • German equatorial design for smoother and more accurate tracking
  • Center-balanced "Z"-design: Weight is placed over the center of gravity for greater stability, smoother movement, and quieter running
  • 27 lb payload capacity, excluding included counterweight
  • 0-60° latitude; ±10° azimuth adjustment range
  • Built-in 32-channel GPS receiver for accurate day, date, time, and location information
  • Spring loaded Vixen-style dovetail saddle
  • Adjustable polar alignment even during tracking
  • Retractable counterweight bar prevents obstruction by the tripod; 20mm diameter accepts any compatible weights
  • Includes 10.4 lb counterweight
  • Integrated bubble level
  • Works in the Northern and Southern hemispheres
Motors and Gears
  • Improved periodic error over previous model, reduced to less than ±10 arcsec
  • 1.8° stepper motor with 128x microdivision
  • 88mm, 144-tooth aluminum R.A. and DEC worm wheels
  • Brass worm gears
  • 55mm R.A. and DEC ball bearings provide smooth movement with minimal vibration
  • 35mm steel R.A. and DEC axis shafts
  • Synchronous belt transmission improves tracking accuracy, with reduced vibration - especially with heavy loads
  • R.A. and DEC gear switches release the gears for balancing OTA
  • Gear tension adjustment eliminates play in gears
  • Resolution: 0.17 arcsec
  • Low-power consumption: 0.35A (tracking), 0.6A (using GoTo)
  • Runs on included 110- 240 VAC power adapter

  • Real-time Periodic Error Correction (PEC) eliminates tracking errors for long-exposure astrophotography
  • Tracking rates: Sidereal, Lunar, Solar, King, user-defined from 0.99x to 1.01x of Sidereal
  • Track Below Horizon option allows mount to track objects below the horizon that are still visible, such as if observing from a hill or rooftop/balcony
  • Computer control with planetarium software via integrated autoguiding port
  • Adjustable key and display brightness
  • Control for optional electronic focuser
  • Control optional illuminated polar scope light intensity
  • Fully compatible with mount's integrated GPS module to automatically determine day, date, time, location
