iOptron GEM28 with iPolar and 1,75" LiteRoc tripod (SKU: G281A3)

The iOptron GEM28 is an advanced equatorial mount (EQ) specifically designed for professional visual observations and astrophotography. With its use of high-quality materials and innovative design solutions, iOptron engineers have created a product that sets new standards in the realm of lightweight mounts capable of carrying heavy loads.

The assembly's metal head houses a precise drive system comprising high-resolution stepper motors. These motors transmit torque to the declination and right ascension axes via a belt transmission, ensuring smooth and accurate movement. The advanced system of permanent correction of periodic error guarantees the highest level of guiding precision, with an error value of less than ten arc seconds.

The GEM28 mount is designed to work seamlessly with the Go2Nova® 8409 controller. This controller boasts an extensive database of over 212,000 celestial objects, providing users with unparalleled observation possibilities. It allows for countless hours of exploration and enjoyment of the breathtaking views offered by the night sky. Additionally, the assembly includes the iPolar ™ electronic polar finder, which simplifies polar alignment.
