Skywatcher Long Eye Relief 5mm
Sharp down to the diffraction limit of the measurement system in the center, slightly blurred at the edges.
x-axis: distance from optical axis in °, y-axis: resolution in arc minutes
Apparent Field of View:
Field of view is just approx. 37°.

Noticeable cushion distortion.
Good quality with rubber eye guard, grip coated body.
Not a bad eyepiece, but the small apparent field of view and the distortion are contrary to a really good rating.
