Skywatcher Super Ploessl 7.5mm

Sharpness is very good within 30° apparent 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. 44°.

Contrast:

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

Aberration:

Nothing noticeable.

Eye Relief:

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.

Mechanical Quality:

Fine. You do not need more to keep it for a long time.

Summary:

A very good eyepiece, especially at this short focal length. Recommendable.
