The 2" diameter barrel 100°-Series 5.5mm Eyepiece from Explore Scientific is an ultra-wide field telescope eyepiece designed for planetary and deep-space observations. Its wide exit pupil makes this eyepiece ideal for comfortable viewing for extended periods. The contrast is enhanced by a fold-down rubber eyecup that prevents stray light from leaking into your eye. Anti-reflective multicoated optics ensures bright, high-contrast images with true color transmission across the entire wide field of view. The eyepiece features a textured surface for a sure-grip when changing it out, argon-filled body for water and fogproof performance when used in extreme temperatures and climates, and a double-tapered barrel for smooth insertion and removal from the focuser.

Ultra-wide 100° apparent field of view displays a broad image with minimal optical distortion, ideal for detailed observation
Images have true color transmission across the entire field of view, even as the observed object approaches the field stop.
Anti-reflective multicoated optics ensure bright, high contrast images
Wide exit pupil, long eye relief ensure comfortable long-duration observation through your telescope
Double-tapered barrel allows smooth insertion and removal from the telescope's eyepiece holder or diagonal

Protection with days of white residue
Style: SPF 50 Roll On, Size: 3 Fl Oz (Pack of 1)
Mineral sunscreens have yet to master blending in and this is no different. If you're thinking of hitting the beach with your sexy bum protected it'd better be a ghost beach because you'll look like you've been dipped in white paint. Oh, and it doesn't wash off, so be prepared to look like Casper for days to come. It rolls on fine if you shake it well first and it does protect.
