TS Super Ploessl 6mm
Good within about 30° field of view. Things are getting worse to the edges.
x-axis: distance from optical axis in °, y-axis: resolution in arc minutes
Apparent Field of View:
The apparent field of view is approx. 56°.
Very good contrast because of good multicoating and use of just four lenses.
Very short eye relief because of the short focal length. Viewing the complete field of view is not possible without looking into the eyepiece under different angles.
Nice. You do not need more to use it for a long time.
Recommended for planetary observations.
