Introducing the Stellarvue Optimus eyepiece series. 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.
A 100 degree field of view provides the user with almost 1.5 times the area of an 82 degree 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 nine elements is fully multi-coated, edge blackened and the lens barrel and baffles are similarly dark black. All of these factors add up to create an extremely contrasty eyepiece that is free of unwanted reflections, flaring or ghosting.This is a superb eyepiece for moderately low power and wide fields with the contrast normally seen at much higher powers.
