Art. –Nr. SKY-PL-06.3
Skywatcher Ploessl 6.3mm
Sharpness is good, also at the edges. The center is definitely not as sharp as the surrounding 10° 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°.
Good, but not very good.
Slight cushion distortion. Not really a drawback.
Short eye relief, but despite that the look into the eyepiece is comfortable.
Simple, but not bad. Without rubber eye cap. The filter thread is not blackened.
This is clearly an eyepiece in the lower price range. However, beginners may use it without too much loss in optical performance.
