Explore Scientific 62° Series 40mm Long Eye Relief Eyepiece (2")

Explore Scientific engineered this 62° Series 40mm Long Eye Relief Eyepiece to address a common concern during astronomy sessions: Contact with the eyepiece causing unwanted vibrations that interfere with your viewing experience. The eyepiece's long 28.2mm eye relief places the eye far back from the lens surface, thus avoiding contact, while allowing for tack-sharp focusing. Image quality is enhanced through the use of a 5-elements in 3-groups lens configuration and anti-reflection fully multi-coated optics. This model of the 62°-series comes with a 2" diameter barrel that fits into common drawtubes, and accepts most eyepiece filters. The housing is argon-filled and O-ring sealed to be water and fog-proof, and has a textured ring on the exterior to give it a secure grip.
