The mount can carry a payload of up to 12.7 kg and offers an optimal payload to weight ratio (2:8).
This ratio allows a fairly high payload with a low mount weight: these are ideal conditions for your astronomical photography and observation outings.
In the new GEM28, iOptron has incorporated additional useful features for more comfortable use and advanced functionality.
With a built-in wifi system (easy to use even when wearing gloves) and an integrated WLAN, this model records the periodic error permanently (PPEC protocol).
In terms of functionality, the GEM28 offers precise approach and very accurate tracking of objects.
The GEM28 is also equipped with the latest Go2Nova® technology, making it one of the most powerful and accurate GoTo technologies on the market.
The database of 212,000 objects ensures that you will never run out of targets in the sky.
Operation of the Go2Nova® control knob is intuitive and the large four-line LCD display makes it easy to set up the mount and locate objects.
The GEM 28 is equipped with either the optical "AccuAlign" or electronic "iPolar" Polar finder.
