Losmandy GM811G Equatorial Mount with LW Tripod & Gemini GoTo System - GM811G

SKU: LOS-GM811G
 

Losmandy GM811G Gemini 2 Equatorial Mount with Tripod

At a very generous 50 pounds, the Losmandy GM811G Equatorial Mount has almost twice the load capacity of the classic GM-8, and as always, it is one of the most precise and finely crafted telescope mounts available today. Made completely in the USA, the modular Losmandy GM811G GoTo Mount includes a G11 RA axis and a GM8 Dec axis, and the motors are "tucked in" for a more streamlined look. A spring-loaded worm has been added to the RA and DEC axis. Precision machined from aluminum and stainless steel (no castings here!), this work-horse provides astrophotographers and visual astronomers alike with a solid platform and Gemini 2 computerized goto electronics for years of pleasure.
