Evoguide 50DX APO- S11174

Sky-Watcher EvoGuide 50DX APO Guide Scope Sky-Watcher has designed this lightweight guide scope to deliver excellent views of planetary and deep-sky phenomenon. The doublet refractor delivers dramatic black skies with high contrast for celestial objects. Mounting this guide scope is extremely easy. The included M42 rings on the back of the guide scope secures the connection and the signal-speed focus ring helps pinpoint that perfect focus. The design was initially intended for guide cameras, but the EvoGuide 50 DX APO Astrograph Guide Scope can also be used for fast, low focal length astrophotography when used with a focal reducer (not included). This guide scope comes with tube rings, a finder stalk, and a Vixen-style mounting plate.
