USED Losmandy GM8 Equatorial Mount with Tripod and Digital Drives

Used but very well cared for mount in very good condition. This mount has no goto functionality; it is the basic package with a stepper motor on each axis. It can still be autoguided and used for astro-imaging as is by plugging an autoguider into the hand control port. Also, it can be upgraded to a fully goto mount with Losmandy's Gemini II retro-fit kit. There are no boxes with it, in-store pickup only.

Trust Losmandy for exceptional robustness and high build quality. Losmandy equatorial mounts are best-in-class. They are designed for the astronomer who demands unyielding performance from his equipment.

The Losmandy GM8 is great for small-to-medium sized instruments, for visual observation and astro-imaging.
