Losmandy GM8 G Equatorial Mount

Losmandy GM8 G

If you are looking for an equatorial mount for imaging for your 8″ SCT , Refractor or up to an  8″ Newtonian, with smooth operation, minimal PEC and looks like a million dollars without costing a million dollars then this is the mount for you.

Scott Losmandy has been manufacturing high quality, precision German Equatorial mounts for nearly 20 years now.  His Losmandy mounts are highly regarded for their innovative mechanical designs.

Manufactured using computer controlled equipment operated by an experienced staff results in a degree of consistency and performance that is unrivaled in its price range.

The result for the user is a mount that tracks as it should with minimal Periodic Error – these mounts are a dream come true for astrophotographers.

Features

Fully locking, unique tangent arm design altitude adjustment, 6-68 degrees, large knob for easy alignment.

Laser engraved latitude scale in 2 degree increments.

Single knob azimuth control, bi-directional +/- 8.5 degree.
