Soligor ED 12.5mm
Very good sharpness for the whole field of view. However, you will get a blurred image at the edge if not looking into the eyepiece under the correct angle (see eye relief).
x-axis: distance from optical axis in °, y-axis: resolution in arc minutes
Apparent Field of View:
The apparent field of view is approx. 50°.
Comfortable at the center of the field of view. A minus for the effect, that you have to look into the eyepiece under a certain angle to get a really sharp image.
A very good manufactured eyepiece of high quality.
A long eye relief eyepiece of high quality. Surely worth its money, but not the best one of this series.
