Art. –Nr. SKY-SP-26
Skywatcher Super Ploessl 26mm
Very good sharpness, just close to the edge not perfect.
x-axis: distance from optical axis in °, y-axis: resolution in arc minutes
Apparent Field of View:
Field of view is approx. 46°.
Due to the multi coating and use of just four lenses a very good contrast.
Close to the edge slight cushion distortion.
Comfortable at this long focal length.
Fine. You do not need more to keep it for a long time.
A good eyepiece in any way, but not the right one if you like to have a big apparent field of view.
