Our winged rubber eyecups are the ideal companion for most 1¼" Eyepieces. The winged extension completely blocks out extraneous light from the periphery more completely and more comfortably than the typical rigid or foldable 360degree eyecups supplied with even high-end eyepieces. It is much easier to concentrate on the image and to see faint objects, while imparting a more 'intimate' view, isolated from distracting side-light. We find these to be outstanding for binoviewing. The winged extension folds down for more compact storage.
# EYECP-1 Winged Rubber Eyecup 1, fits eyepieces with barrel sizes of approximate diameter 31 - 32.5mm.
# EYECP-2 Winged Rubber Eyecup 2, fits eyepieces with barrel sizes of approximate diameter 33.5 - 34mm. This is the most common size and fits most standard Plossls, as well as the Baader Genuine Orthos and the new Zeiss Abbe-II Eyepieces.
* This size is also ideal for use with Nagler Type6 eyepieces, giving more usable eye relief, greater comfort, and much better cutoff of extraneous light than the stock eyecup, esp. for binoviewer use. The stock lens cap still fits (with eyecup folded down).
|# EYECP-4 Winged Rubber Eyecup 4, fits eyepieces with barrel sizes of approximate diameter 40.5 - 41.5mm.|
