Stellarvue 20 mm 100° 2" Optimus Extreme Wide Angle Eyepiece
This is the Stellarvue 100° FOV 20 mm Optimus Extreme Wide Angle Eyepiece. This 20 mm eyepiece is ideal for viewing of extended objects, scanning the Milky Way, and locating objects using the widest possible field of view. This eyepiece will give you those wide field images of the sky you want when searching for objects or when teaching friends and family about the sky, star-hopping, the Milky Way, etc. It will maintain the high contrast for which Stellarvue telescopes are famous.
A 100° field of view (FOV) provides the user with almost 1.5 times the area of an 82° eyepiece. When using hand driven alt-azimuth mounts this generous field will be appreciated. The eyepiece offers a generous 15 mm of eye relief and has a standard foldable rubber eye cup. Each of the eight elements are fully multi-coated, edge blackened, and the lens barrel and baffles are similarly dark black. All of these factors help to create an extremely contrasty eyepiece that is free of unwanted reflections, flaring or ghosting, with the resolution you expect from Stellarvue.
This is a great eyepiece for viewing nebulae, star clusters, and galaxies!
The EOP-20.0 Eyepiece is for use with a 2" eyepiece holder on a scope. The Optimus series of eyepieces from Stellarvue are all weatherized in that the outer lenses are sealed!
