The Celestron Luminos 31mm is a high quality, very low power eyepiece, using a seven-element fully-multicoated optical system. It provides a very wide 82° field of view for telescopes with 2″ focuser/star diagonals.
The Luminos series provides the widest field of view of eyepieces offered by Celestron, without using a binoviewer. The eyepiece has a retractable eye guard that raises and lowers, by turning the rubber grip ring. The no-slip rubber grip ring means a secure and comfortable grip when handling in cold weather. The Celestron Luminos 31mm comes with dust caps for both ends of the eyepiece and a bolt-type plastic storage case.
