iOptron Mount GEM28EC LiteRoc (74331)

The iOptron GEM28 is a lightweight and portable German equatorial mount designed for ease of handling and transport. Despite its compact design, the mount can carry loads of up to 12.7 kg, offering an impressive weight-to-load ratio of 2.8. This makes the GEM28 ideal for mobile astrophotography and visual observation, as it balances portability with high load capacity.

iOptron has incorporated advanced features into the GEM28 for enhanced user comfort and functionality. The mount includes built-in WiFi for seamless connectivity and permanent periodic error correction (PEC), ensuring stable tracking performance. With precise pointing and exceptionally accurate object tracking, the GEM28 sets new standards for medium-sized equatorial GoTo systems.

The GEM28EC version is equipped with iOptron's latest Go2Nova® technology, making it one of the most powerful and precise GoTo systems available. Its database of 212,000 celestial objects ensures a wide variety of targets for observation and imaging. The intuitive Go2Nova® hand controller features a large four-line LCD display, simplifying setup and object location.

Additionally, the GEM28EC includes an electronic iPolar system for precise polar alignment, even when the Pole Star is not visible.
