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 eye relief – also suitable for spectacle wearers, the fold-able eye-rubber allow a comfortable view. All lenses (9 lenses in 5 groups) have a broad-band multi-coating (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.

  • 2 “connector with integrated filter thread
  • Large upper field lens for comfortable optical insight
  • Suitable for eyeglasses users
  • Border Sharp Image High quality multi-coating ideal for optics with medium or long focal length
