XW Eyepiece 20mm
The Pentax XW eyepieces are suited for practically all possible observations - be it extended deep sky objects with an excellent image sharpness over the entire field of view or planets for which sharpness on the optical centerline is most important - the Pentax XW eyepieces will excel in all these situations. 

The comfortable eye relief and ergonomic design offer relaxed observing conditions for long periods without tiring the user. You can observe both extended objects and small, high power objects. The excellent contrast and light transmission (approx. 98%) make light contrasts and small details discernible. 

The eyepieces are weatherproof according to JIS class 4. This signifies a particularly robust coating and eyepiece body.
