Very good over the complete field of view.


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


Apparent Field of View:

The apparent field of view is approx. 36°.



Very good contrast because of good multicoating and use of just four lenses.



Slight cushion distortion, nearly not noticeable.


Eye Relief:

Comfortable at this long focal length.


Mechanical Quality:

Nice. You do not need more to use it for a long time.



Nice eyepiece. But not the right one, if you would like to have a large apparent field of view.
