TS Wide Angle 42mm
x-axis: distance from optical axis in °, y-axis: resolution in arc minutes
Apparent Field of View:
The apparent field of view is approx. 54°, much less than given by the manufacturer.
Very good contrast.
Slight cushion distortion.
Nice quality with foldable rubber eye cup and grip coated body.
A recommendable 2-inch eyepiece, just a minus for the small apparent
field of view. Do not use with faster optics than F/6 because of the large exit
