Sky-Watcher K100 Klevtsov-Cassegrain Optical Tube Assembly

The Sky Watcher K100 Klevtsov Cassegrain is a 100mm catadioptric optical tube built around a 1000mm focal length at f10. It folds a long optical path into a short, easily handled tube, making it well suited to high magnification viewing of the Moon, bright planets, and close double stars. The mirror based design stays well balanced on light mounts while keeping contrast high and the setup straightforward.
