Mount APM GE-200

Our professional APM GE-Series mountings start at a point where at other manufacturers mounts the carrying capacity is too low.

The APM GE 200 has hollow shafts with a inner diameter of 63mm and an outer diameter of 100mm which are mounted in high precision 32mm wide cone-bearings in front with a inner diameter of 100mm and an outer diameter of 150mm and on the back with a inner diameter of 90mm and an outer diameter of 140mm. So the mount has a very high photographic carrying capacity of 330 lb.

This mount has been developed for large Cassegrain telescopes and Hypergraphs from 20" aperture onwards, but is also a perfect match for long and heavy refractors like our large APM-LZOS apo refractors.

For transport you can seperate the declination axis from the right ascension axis, so it's a lot easier to handle the 500 lb weighing mount. The mount is equipped with high precision wormwheels with 280mm diameter for a extrem precisely tracking. Alternatively you can get as an option a friction wheel drive. Very interesting are the extrem smooth adjustable friction clutches, which you can easily handle with a small grip.

In the basic configuration you will get this mount with the Sideres STAR-CONTROL Mount Controller for GoTo operation. This controller has various possiblities to control the mount.

Optional: Equatorial Pier for GE 200 with 1,5m Height
