APM Ultra Flat Field 30mm Eyepiece 70° FOV
This is a High-quality eyepiece with long focal length! The 2″ Ultra Flat Field 30mm Eyepiece features a high quality standard and a very compact design, which is designed to remove the field curvature at the edge, resulting in a flat, distortion-free image up to the edge of the visible field of view, even in very fast (for example f/4) telescopes. The eyepiece has over sized eyepiece lenses for the largest possible field of view and a 22mm eyerelief – also suitable for spectacle wearers, the foldable eye-rubber allow a comfortable view. All lenses (9 lenses in 5 groups) have a braod-band-multicoating (FMC) and blackened lens edges. The plug-in sleeve is equipped with a thread for 2 “filters.
The eyepiece is ideal for optics with medium or long focal length.
