The Sky-Watcher optical tube is a Newtonian reflector telescope designed for astrophotography and advanced visual observing. Its parabolic primary mirror and 650 mm focal length allow detailed views of planets and photography of deep-sky objects. The shorter tube design makes it easier to reach prime focus and compatible with a range of mounts.
Focusing is done with a 2" dual-speed Crayford focuser with a 10:1 fine-focus knob. The telescope is suitable for observing the Moon, planets, star clusters, nebulae, and galaxies.
