Art. –Nr. SKY-LE-09
Skywatcher Long Eye Relief 9mm
Poor for a 9mm eyepiece.
x-axis: distance from optical axis in °, y-axis: resolution in arc minutes
Apparent Field of View:
Field of view is approx. 48°.
Between good and very good.
Noticeable cushion distortion. Chromatic errors (colored fringes) towards the edge.
Good quality with rubber eye guard, grip coated body.
The long eye relief lens combination is clearly an optical drawback. Take other eyepieces, if you do not need this long eye relief.
