German Equatorial Mount
In this age of computerized "Go To" mounts, a GEM is pretty Old School... but I like it that way! This critter dates back to the 1960s, and was engineered to carry a LOT of weight... and that was exactly what I needed with this tube.
If you have a computerized mount, you don't learn to read the sky.
A drive corrector has been added to fine tune the sidereal, lunar and solar tracking rates, as well as serve as a battery inverter to power the 110 VAC synchronous motor from a 12 volt gel cell.
