ENHANCES THE PERFORMANCE OF LONG FOCAL LENGTH 2" EYEPIECES ON 10" AND LARGER SCHMIDT-CASSEGRAIN TELESCOPES, INCREASING THE FIELD OF VIEW WHILE REDUCING VIGNETTING
Are you getting all the eyepiece aperture that you paid for? Depending upon the specific 2" eyepiece, an EyeOpener will increase the total amount of light delivered to your eye by as much as 65% - the equivalent of a 2" or more increase in telescope aperture!
What is it?
The Eyeopener (shown between the arrows) is a 2" visual back for 10" and larger Meade and Celestron Schmidt-Cassegrain Telescopes (SCTs). This compact close tolerance black-anodized aluminum back screws onto the telescope's backplate and accepts a 2" diagonal tube or direct mounting of 2" eyepieces. The 2" optics are firmly secured with three non-marring thumbscrews.
