Baader Rubber Eye Shield for 33.5 mm - 34 mm Diameter Eyepieces
Baader Winged Eye Shield - Fits 33.5mm - 34mm Diameter Eyepieces
The Baader Rubber Eyecup 2 is the most common size and fits most standard Plossls, as well as the Baader Genuine Orthos and the Zeiss Abbe-II Eyepieces. This size is also ideal for use with Nagler Type 6 eyepieces, giving more usable eye relief, greater comfort, and much better cutoff of extraneous light than the stock eyecup, especially for binoviewer use. The stock lens cap still fits (with the eyecup folded down).
Baader winged rubber eyecups are the ideal companion for most 1.25" eyepieces. The winged extension comfortably blocks out extraneous light from the periphery, and the wing can be rotated to the position it does the most good. When your eye is protected from light coming in from the side, it is easier to see faint objects. Nothing ruins a good view more quickly than a bright light skipping across the optical surface of the eyepiece! The Baader Winged Eyecup works wonderfully well for binoviewing as well. The winged extension folds down for more compact storage.
