Conceived, designed and built for entry-level to intermediate astrophotographers, the iEQ45 Pro GOTO Equatorial Mount with 42" Pier from iOptron is outfitted with precision motors, zero-backlash gears and a computer controller to provide an ideal platform for imaging. It features a motorized equatorial mount, Go2Nova 8407+ computer hand controller, a 42" rock-solid pier, and an illuminated polar axis scope for faster alignment and set-up. The mount has a dual dovetail saddle that fits both Losmandy and Vixen-style plates for mounting compatible OTAs. With a maximum payload capacity of 45 lb, it can easily hold large telescopes, counterweights, and accessories. The mount has a built-in 32-channel GPS receiver that sends your location and time to the Go2Nova hand controller, so the telescope can be set up quickly with accurate information.
The included dark-field illuminated AccuAligning polar axis scope installs through the body of the mount for accurate initial manual alignment, and alignment verification and correction during observation and imaging sessions. The iEQ25 is built for precise tracking, as required during long-exposure astrophotography, with highly accurate stepper motors and the ability for you to program out the Periodic Error Correction (PEC) common to all worm gears.
The dual-axis 1.8° stepper motor is controlled by the Go2Nova hand controller. This system has an internal database of 359,000+ celestial objects, with 60 user-defined objects to program yourself. The hand controller has 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 no matter if you're viewing the fast-moving Moon or much slower deep space subjects.
A 42" pier is included for the mount and your telescope. The pier provides a more stable base than most tripods with greatly reduced vibration. The components for the pier, including the legs and pull-rods are stored in the pier tube when not in use. If you have a permanent observation location, setting up a pier is ideal.
