The image is well corrected and sharp from edge to edge. There is a slight loss of contrast in lunar and planetary observing when compared to an eyepiece with fewer elements, due to the additional lenses needed to achieve the unique combination of short focal length and very wide field. The loss is minimal though, on a par with the contrast loss in an eyepiece/Barlow combination with the same effective focal length. In the eyes of many observers, the “picture window on space" observing experience of its exceptionally wide field more than makes up for any slight contrast loss.

The eyepiece comes close to the optimum 1mm exit pupil that most closely matches the resolution of your eye to that of a Schmidt-Cassegrain telescope. This makes it a good choice for critical observing with this type of scope.
