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.
