( Product Infomation Posted On Time : Mar 26, 2012 18:13:52 View Last Update Infomation At Amazon)

Enjoy a wide-field window into the heavens served up by Stratus eyepieces. With an apparent field of 68-deg -- which translates to a 71% greater viewing area than that of a typical Plossl -- Stratus eyepieces quite literally put more stars in your eyes. In the same way you feel more a part of the action watching a big-screen TV, with Stratus you will feel like you are really experiencing your celestial targets, rather than just viewing them from afar. Each ocular features a monster 1-1/4"-diameter eye lens to look into. Each also has a generous 20mm of eye relief, so you'll get the big picture even if you wear eyeglasses. The optics are fully multi-coated to maximize light transmission to your eyes, and the lens edges are blackened to ensure excellent contrast. Stratus eyepieces fit in both 1.25" and 2" focusers. Each is threaded for filters and comes with protective lens caps.
