  1. Pentax 8-24mm SMC 1.25" long eye relief astronomical zoom; 21-63x or 26-78x spotting scope zoom

    This is an ultra-premium six-element zoom eyepiece with surprisingly good eye relief for those who must wear eyeglasses while observing. Designed for use with Pentax spotting scopes, it can also be used for astronomical observing in any telescope accepting 1.25" accessories . . .

    Unlike an ordinary zoom eyepiece, this high power Nagler zoom maintains a constant and substantial 50 degree apparent field of view at all focal lengths and the usable eye relief stays a constant 10mm . . .
