Soligor Ploessl 9mm
Good sharpness, close to the edge a bit worse.
x-axis: distance from optical axis in °, y-axis: resolution in arc minutes
Apparent Field of View:
The apparent field of view is approx. 46°.
Comfortable if the rubber eye cup is folded back.
Like the Skywatcher and TS Super Ploessls.
Sharpness could be a little bit better, however it is a recommendable eyepiece.
