Art. –Nr. RE-UWA-30
Ultra Wide Angle 30mm
Very good at the center, somewhat worse to the edge.
x-axis: distance from optical axis in °, y-axis: resolution in arc minutes
Apparent Field of View:
Our measurement gives 72° - somewhat less than the manufacturer data.
Very good contrast.
Noticeable cushion distortion and field curvature.
Not even huge, but comfortable viewing distance.
Simple, but good quality with rubber eye guard, grip coated body. Fully multicoated and blackened inside.
This is a very low-priced 80° panoramic eyepiece. At F/5 you will find 50 to 60% of the field in very good image quality, up to the edges “comet tails” become prominent. The field curvature is obviously contrary to that of a Schmidt-Cassegrain, which makes this eyepiece especially recommendable for these type of telescopes. This eyepiece is known as “BW30” or “Moonfish” also.
