Art. –Nr. SKY-SP-40

Skywatcher Super Ploessl 40mm



Very good sharpness, better at the edge than in the center.


x-axis: distance from optical axis in °, y-axis: resolution in arc minutes


Apparent Field of View:

Field of view is approx. 36°.



Due to the multi coating and use of just four lenses a very good contrast.



Close to the edge slight cushion distortion.


Eye Relief:

Comfortable at this long focal length.


Mechanical Quality:

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.
