DESCRIPTION

Losmandy GM-8 Equatorial Mount with Tripod

If you would like a good equatorial mount that can handle your observing and imaging requirements, the Losmandy G-8 is definitely worth a look. This heavy-duty digital mount is machined of aluminum and stainless steel, utilizes all stainless steel hardware and has a load capacity of 30 pounds.

The telescope attaches to the mount via a dovetail bar bolted to the bottom of the telescope.

 

The various parts that make up the Losmandy GM8 Equatorial Mount:

Once the telescope is set up, you will need to point it at various locations to observe different objects. Unlike other mounts, the Losmandy mounts have a clutch system. To make rough adjustments, loosen the R.A. and DEC clutch knobs slightly and move the telescope in the desired direction. The R.A. clutch knob is near the Polar Axis Finder while the DEC clutch knob is at the top of the counterweight bar. How tight should the clutch knobs be? You set the clutch knobs to the friction you like. When you want to move the telescope, all you do is grab the telescope and move it to its new position.

Note: Before you attach the optical tube, make sure that the declination and right ascension clutch knobs are tight. This will ensure that the mount does not move suddenly while attaching the telescope.
