The iEQ45 Pro GOTO German equatorial mount is the next generation premium astro-imaging mounts from iOptron. We've made a few changes on the iEQ45 including:

  • Stepper motor (instead of servo)
  • Higher gear ratio for even smoother tracking

A number of visual changes (plugs moved to sides, motor covers are singular piece, and more) The iEQ45 Pro mount offers the next generation GoTo technology from iOptron --not to mention built-in 32-bit GPS. With a payload of 45 lbs. balanced -- it comes standard with a calibrated dark field illumination polar scope and a sturdy 2-inch stainless steel tripod. It also fits both Vixen and Losmandy-type mounting plates. Its lighter weight (only 25 lbs.) makes it much easier to carry.
