iOptron GEM45G GoTo Equatorial Mount with iGuider & Hard Case

iOptron found that there was a way to remove unnecessary bulk from the mount, resulting in the iOptron GEM45G having an amazing 2.7 payload to mount weight ratio, the mount weighing 15.8 lb. while supporting up to 45 lb. The GoTo technology then can accurately locate and track an object with 45 lb. of equipment attached. This mount utilizes a reliable stepper motor drive system equipped with low power consumption technology to keep things running smoothly. This iOptron German Equatorial mount ties contemporary technology and a classic mount design together in a lightweight and compact package that is sure to please observers and astrophotographers!

The GEM45G has a CNC machined body that has been anodized red and black and includes large levers as part of the quick-lock drive engagement system. These levers give users the ability to snap gears into place, even when the cold nights call for thick gloves. Furthermore, the design of the GEM45G mount has an advanced, internal cable management system that will greatly minimize the risk of cables getting snagged during tracking.

About the G Version of the GEM45 Mount

The iOptron GEM45G is the G version of the popular GEM45 mount! The G version comes with an onboard guiding camera called the iGuider. The iGuider from iOptron is made of a 30mm F4 lens and a 1/4 CCD with 3.75 um pixels. The lens and sensor are all conveniently tucked away in the mount saddle. This version comes with a 6" dual saddle, a single USB cable connection for your computer from the cable management system and a larger diameter counterweight shaft than the original version of the iOptron GEM45 mount. This version of the GEM45 mount does not come with the optional visual polarscope kit.

About the GoTo Technology

An integral part of this compact, lightweight mount package is the GoTo technology. Using the Go2Nova® 8407+ controller with a built in heater gives users access to a 212,000+ object database and star identification. Tacking technology like the type used with the GEM45G mount means observers can spend more time observing and less time finding their desired celestial objects. Using this equatorial mount and the tracking capabilities makes this an ideal tool for taking long exposure images.

About the Included LiteRoc Tripod and Hard Case

Included with the GEM45 mount is a 1.75" LiteRoc tripod. This tripod has 1.75" stainless steel legs, providing stability for the mount while it tracks and supports the viewing equipment. This mount is additionally compatible with the iOptron 900 mm Permanent Pier (IOP-8038-900) when used in conjunction with the iOptron Mini Pier Tripod Extension (IOP-8032) or iOptron 6" Pier Top Plate (IOP-8032-PT) for those looking for a pier solution (pier, mini pier, and top plate sold separately).

The included hard case will help keep your mount protected from the elements during times of travel and storage.
