With a head design and precise synchronous belt transmission that improve tracking accuracy with reduced vibration, the iOptron GEM28 GoTo EQ Mount makes an ideal mount for your astronomy and astrophotography needs when using small to medium refractors, reflectors, or Cassegrain optical tubes. Its combination of powerful computer hand controller, iPolar electronic alignment scope, and integrated Wi-Fi module, will enable you to spend less time aligning your mount and more time enjoying the wonders of the universe. In addition to the mount head, you also get a solid, yet stable, stainless steel tripod to support your gear and a hard carrying case for the mount head and accessories like the hand controller.
Mount
- Ideal for small to medium sized refractors, reflectors, and Cassegrain optical tubes

- <±10 arcsec of periodic error that can be trained out over time with PPEC function on hand controller
- 28-pound payload capacity, excluding included counterweight
- 10-70° 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 Wi-Fi module allows you to control the mount via smartphones running controller app
- 3.8" Vixen-style dovetail saddle
- Retractable counterweight bar prevents hitting the tripod or otherwise interfering with the mount's movement; 10-pound counterweight included

Motors and Gears
- Synchronous belt transmission improves tracking accuracy, with reduced vibration, especially with heavy loads
- Less than ±10 arcsec periodic tracking error
- 1.8° stepper motor with 128x microdivision
- 88mm, 144-tooth right ascension (RA) and declination (dec) aluminum worm wheels with zero backlash
- 55mm RA and declination ball bearings provide smooth movement with minimal vibration
- 35mm steel RA and dec axis shafts
- RA and declination gear switches release the gears for balancing OTA
- 0.17 arcsec motor resolution
- Low-power consumption: 0.6A (tracking), 0.9A (using GoTo)
