Art. –Nr. SKY-SP-06.3
Skywatcher Super Ploessl 6,3mm
Sharpness is good nearly for the full field of view. Only close to 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. 46°.
Only good contrast.
Very short eye relief because of the short focal length. To have a view of the whole apparent field of view you have to get very close to the lens.
Fine. You do not need more to keep it for a long time.
Still a good eyepiece, but the 7.5mm version is clearly better.
