Art. –Nr. RE-SWA-38
Super Wide Angle 38mm
Very good at the center, but towards the edges at little bit worse.
x-axis: distance from optical axis in °, y-axis: resolution in arc minutes
Apparent Field of View:
Our measurement gives 61° - that is less than the manufacturer data.
Slight cushion distortion.
Good quality with rubber eye guard, grip coated body. Fully multicoated and well blackened inside.
Recommended as a 2” panoramic view eyepiece as long as you are not expecting really pin-point stars close to the edges. However, not recommended for telescopes with focal ratio faster than F/6. Even the exit pupil will become to big with fast telescopes.
