Welcome to Dark Sky Observing in Overgaard, Arizona.

I have several telescopes on German Equatorial Mounts (GEM) and one Dobsonian for sale, plus, many telescope making components. Additionally, a massive GEM with dual Byers drive gears, an Astrola GEM head, and an antique refractor project.

Everything is cash and carry, with pickup in Overgaard, AZ. We cannot deliver. Prices negotiable. Email for more details and availability.

SOLD - This massive GEM is a new-construction equatorial head. Professional aluminum welding, even the RA gear cover has amazing welding. The pier is custom as well. The shaft casings are 4.5", Dec shaft 1.5" and RA is 2". The Byers are Dec 7.5" and 10" on RA. The RA has been used but Dec has never been used as the Dec Byers motor leads are factory-tinned. There is no scoring on the Dec shaft from counterweights ever on it . There's $1000 in just the Byers gears..... The mount is on wheels and has leveling screws included.

Price; $500!!! SOLD
