Vixen NPL 30 mm 1.25" eyepiece

The 2-group 4-element Plossl design of Vixen's NPL Series delivers bright, sharp views with high contrast and good colour correction. The 20mm, 25mm, 30mm and 40mm models feature twist-up eyecups. All have fully-multi-coated optics. Affordable eyepieces that offer a noticeable improvement over generic Plossls supplied with most telescopes.  Threaded barrel accepts 1¼" filters and features a 'safety undercut' to prevent the eyepiece falling out of the focuser.

30mm and 40mm: Due to the 1¼" barrel size the 30 and 40mm eyepieces show almost the same area of sky so, for visual use, the 30mm is the better choice. The 40mm is however useful when a compact camera is positioned over the eyepiece for afocal photography.
