Tele Vue eyepieces come in several variations and focal lengths to match your particular preferences amongst the variables of size, weight, price, eye relief and apparent field of view. They're universally applauded by both amateur and professional astronomers alike, and hold their resale value incredibly well.
The Plossl 40.0mm eyepiece is a venerable "entry level" classic amongst Tele Vue eyepieces. It is characterized by having a super sharp, relatively narrow 43° apparent field of view with sufficient eye relief. It is lightweight for its focal length and ideally suited for work in Tele Vue's Bino Vue Stereo Binocular Viewer.
