Losmandy GM8 Equatorial Mounting

The GM8 is the smallest of the Losmandy range of Equatorial mountings. It features the same high build quality as its larger brother the G11 but in a lighter and more portable form.

Like the G11 the GM8 is available with the Gemini 2 mini controller or Losmandy's dual axis drive (non goto) system.

The GM8 is ideal for customers wanting a high quality and well engineered portable GEM for both visual use and astrophotography.

The mount features a 2.812 diameter, 7075 aluminum worm gear with 180 teeth.

The GM8 features a dual supported, ball bearing housed ground High Precision Brass Worm. 3.5 diameter laser engraved setting circles, 6 minute R.A. / 2 degrees DEC.

The R.A. circle is engraved for Northern and Southern Hemisphere.

The Dovetail saddle-plate fits both "D" Losmandy Style Dovetail or Vixen Style Dovetail. Allows for the interchanging of any tube assembly-reduces need for DEC. weights.

Includes a fully locking, unique tangent arm design altitude adjustment, 6-68 degrees with large knob for easy alignment.

Laser engraved latitude scale in 2 degree increments.

Also included is a removable stainless steel 1-1/4 inch diameter weight shaft w/safety knob and
7 lb counterweight.

11 lb and 21 lb extra counterweights available.

The Gemini 2 Mini Controller is highly recommended. It offers a huge range of functionality as befits a modern high performance drive controller.

It is internally powered by a battery and thus will not lose synchronisation on the sky in the event of a power cut.
