DESCRIPTION

Orion 3.5mm Stratus Wide-Field Eyepiece - 1.25" / 2"

Orion 3.5 mm Stratus Wide-Field Eyepiece

Enjoy a wide-field window into the heavens, served up by Stratus eyepieces. With an apparent field of 68-degrees, which translates to a 71-percent 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 1.25-inch diameter eye lens to look into. Each also has a generous 20 mm 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-inch and 2-inch focusers. Each is threaded for filters and comes with protective lens caps.

  • IM LOOKING FOR A 2" LO MM EYEPIECE. I LIKE THE VIEW OF THE 2" BUT THIS BEING A 1.25 AND A 2" I DON'T FEEL I WILL GET A TRUE 2" VIUE.. AM I RIGHT? IT MAKES SENSE TO ME... TELL ME THE TRUTH.

    The Orion Stratus 3.5mm eyepiece has an apparent field of 71 degrees. The true field of view through your telescope depends on the magnification. To calculate true field you divide the apparent file by the magnification. For example if you have a telescop
