x-axis: distance from optical axis in °, y-axis: resolution in arc minutes

Apparent Field of View:

Field of view is approx. 44°.

Contrast:

Due to the multi coating and use of just four lenses a very good contrast.

Nothing noticeable.

Still short eye relief because of the short focal length. To have a view of the whole apparent field of view you have to get close to the lens.

Fine. You do not need more to keep it for a long time.

A very good eyepiece. Recommendable.
