iOptron GEM28 GoTo LiteRoc Mount

Like most iOptron GEM models, the new GEM28 has been designed with convenient portability in mind.

The mount can support a payload of up to 12.7 kg and offers an optimal weight-to-payload ratio of 2.8.

This ratio allows for a relatively high payload with low dead weight, creating ideal conditions for mobile astrophotography and observation.

iOptron has incorporated additional features that provide great user comfort and advanced functionality into the new GEM28.

An integrated WiFi system (easy to use even while wearing gloves) and an integrated WLAN that now permanently records periodic error with worm gears (PEC protocol).

In terms of performance, the GEM28 offers precise movement and extremely accurate object tracking. The GEM28 therefore sets new standards for mid-sized equatorial GoTo systems.

Once again, the GEM28 is equipped with the latest Go2Nova® technology, making it one of the most powerful and precise GoTo systems currently available on the market.

The database of 212,000 listed objects ensures that you will never run out of objects to observe in the sky....

The Go2Nova® hand controller is intuitive to use, and its large four-line LCD display makes setting up the mount, as well as searching for objects, incredibly easy.

The GEM28 is equipped with the "AccuAlign" optical polar scope or the electronic "iPolar".

The advantages at a glance:

• Latitude range from 10° to 70°.
