17mm Nagler - Type 4

The Nagler eyepiece represents the ultimate in the visual stargazing experience. With an 82-degree field of view, and tack-sharp, high-contrast optics, nothing compares to the view of the heavens through these eyepieces. The new Type IV Naglers have a handy click-stop Instajust eyeguard to block stray light. The 17mm Nagler makes an excellent medium-power eyepiece on a Schmidt-Cassegrain, Newtonian or one of TeleVue's own refractors with a 2" focuser or diagonal.
