What's Included With This Item:

- Barrel Caps
- Orion 1 Year Limited Warranty
The Orion 5mm Stratus Wide-Field Eyepiece comes with an apparent field of 68° - which translates to a 71% greater viewing area than that of a typical 52° Plossl - this eyepiece quite literally puts more stars in your eyes. In the same way you feel more a part of the action watching a big-screen TV, with this Stratus "sixty-eight" you will feel like you are really experiencing your celestial targets, rather than just viewing them from afar.
This ocular has a sophisticated eight-element optical configuration that features a monster 1-1/4"-diameter eye lens to look into. It has a generous 20mm 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. This Stratus eyepiece fits in both 1.25" and 2" focusers. It sports fold-down rubber eyeguards and a knobby rubber grip. The chrome barrel features a setscrew security recess and is threaded for filters. The eyepiece comes with protective lens and barrel caps.
