This is the Sky-Watcher 50 mm Evoguide APO telescope which has a variety of useful applications. It can be used as a Finder Scope on another OTA, it can be used as a Guide Scope as well, and it can also be used as a small, portable, wide field telescope for different applications including astronomy.

This scope is popular for use as a high-quality finder scope, although it does have the other possible applications mentioned. Sky-Watcher Evostar and Evoguide refractors provide the finest images obtainable in their design class. These doublet refractors deliver dramatic, jet-black skies and faithful, contrast-rich views of planetary and deep-space phenomenon that are second to none.

This Evoguide 50 APO Scope from Sky-Watcher has an aperture of 50 mm and it is an apochromatic (APO) refractor, since it has a matched set doublet lens configuration with one ED element. It has short focal length of 242 mm, at f/4.8 for a wider FOV than a normal telescope. It also incorporates a nice, smooth Helical focuser mechanism with a large, knurled ring for setting the focus. Finally, it includes a double ring set with a riser stalk, so it is easy to mount on your existing OTA or other methods.
