3,5mm Nagler T6 Eyepiece (82 deg.)

 The TeleVue from US has started the revolution of the ultra-wide eyepieces with their Nagler eyepieces in 1979. Following the technical advancements these eyepieces are still represent the top quality for the wide angle eyepieces.

The 82° field of view is three times the field of view of a usual Plossl eyepiece. Although the sharpness is only slightly better at the center than the Plossl eyepiece, the field is much bigger and sharper. Provides the so called \"spacewalk\" feeling, quite different from the narrow-angle eyepieces.

The excellent correction at the edges and minimal ghosting is still valid in fast telescopes, so the eyepieces can be used in F/5 or in F/4 scopes as well. In case of F/4 newtonian telescopes a coma corrector is recommended.

Eyepieces between 2.5mm and 16mm can be fit into standard 1.25\" focusers, while 17mm and up require 2\" focusers.
