Skywatcher Ploessl 25mm
Very good sharpness over the whole field of view.
x-axis: distance from optical axis in °, y-axis: resolution in arc minutes
Apparent Field of View:
Field of view is approx. 48°.
Very good contrast.
Slight cushion distortion. Not really a drawback.
The look into the eyepiece is a little bit uneasy, but not really problematic. You have to stay at the correct point.
Simple, but not bad. Without rubber eye cap. The filter thread is not blackened.
The best one of this series. The optical performance is as good as of more expensive ones.
