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 Nagler Type 4 17.0mm is the ultimate in wide angle eyepiece design. Its 82° apparent viewing field will make you feel as if you're swimming in the view, unaware of your surroundings. It is massive for its focal length and unquestionably expensive, but delivers the pinnacle viewing experience for those that deem the view more important than all other factors. It has remarkably low pincushion distortion.
