the edges a little bit blurred.
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.
Aberration:
Nothing noticeable.
Eye Relief:
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.
