With precision synchronous belt transmission that improves tracking accuracy with reduced vibration, the iOptron CEM40 Equatorial GoTo Mount makes an ideal mount for your astronomy and astrophotography needs—and with a payload capacity of 40 pounds and a Universal Self-Centering Saddle (USCS) that accepts both Losmandy and Vixen-style dovetail plates, it can handle just about any optical tube assembly (OTA) and gear you have.

It includes the motorized mount, the Go2Nova 8407+ computer hand controller, a standard 1.5" tripod, and the iPolar electronic polar finder. The center-balanced design of the mount head places most of the optical tube's weight over the mount's center of gravity, resulting in greater stability, smoother movement, and quieter running versus standard designs. A 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 the precision tracking required for long-exposure astrophotography or observation sessions, the CEM40 has the capability for you to permanently program out the Periodic Error Correction (PEC) common to all worm gears.

The mount is controlled by the Go2Nova hand controller. This system has an internal database of over 212,000 celestial objects, multiple assisted alignment procedures, and updatable 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 configuration provides smooth and accurate celestial tracking for observation or astrophotography
  • Center-balanced "Z" design places the weight over the mount's center of gravity to provide greater stability, smoother movement, and quieter running while requiring less counterweights
  • 40-pound payload capacity, excluding included counterweight
  • 0-60° latitude; ±6° azimuth adjustment range
  • Integrated iPolar electronic polar finder works globally; no Polaris (north) or Sigma Octantis (south) necessary; no need to rotate the mount during alignment
  • Built-in 32-channel GPS receiver for accurate day, date, time, and location information
  • 5" Universal Self-Centering Saddle (USCS) accommodates Losmandy and Vixen-style dovetail plates
  • Retractable counterweight bar prevents hitting the tripod or otherwise interfering with the mount's movement; 10-pound counterweight included

Motors and Gears

  • Less than ±7 arcsec tracking error
  • 1.8° stepper motor with 128x microdivision
  • 110mm, 216-tooth right ascension (RA) and declination (dec) worm wheels with zero backlash
  • 68mm RA and declination ball bearings provide smooth movement with minimal vibration
  • 45mm steel RA and dec axis shafts
  • Synchronous belt transmission improves tracking accuracy, with reduced vibration, especially with heavy loads
  • RA and declination gear switches release the gears for balancing OTA
  • Precise 0.08 arcsec (200 pulse/sec) motor resolution
  • Low-power consumption: 0.6A (tracking), 0.9A (using GoTo)
  • Runs on included 12 VDC 5A power adapter; plugs into a standard 110-240 VAC North American outlet

Go2Nova 8407+ Hand Controller

  • 212,000+ object database includes the moon, sun, planets, stars, comets, asteroids, and constellations
  • Multiple assisted alignment procedures use the built-in GPS module and iPolar electronic polar finder
  • Slew speeds: 1x, 2x, 8x, 16x, 64x, 128x, 256x, 512x, MAX (4.5°/sec)
  • Permanent periodic error correction eliminates tracking errors for long-exposure astrophotography
  • Tracking rates: Sidereal, Lunar, Solar, King's, user-defined from 0.99x to 1.01x of Sidereal
  • Star Identification function will tell user what star the mount is pointed at after proper alignment
  • Computer control with planetarium software via integrated autoguiding port
  • 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, and location
  • Serial port for firmware upgrade
  • Adjustable key and display brightness
  • Integrated heater that ensures the LCD display will work at temperatures as low as -4°F (-20°C)
  • 8-line/21-character LCD screen; backlit 19-button user interface
