If you are one of the legions of folks who have "upgraded" to a big-screen television set lately, then you've probably become spoiled by its wonderfully expansive picture.

Well, if you are a telescope user, you will be equally spoiled by the wide-field window into the heavens served up by this 3.5mm Orion Stratus Wide-Field Telescope Eyepiece. With an apparent field of 68° — which translates to a 71% greater viewing area than that of a typical 52° Plossl, this telescope 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. You'll never go back to Plossls again!

But it isn't just the Stratus' field of view that will widen your eyes. This telescope eyepiece 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 3.5mm Orion Stratus Wide-Field Telescope 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 telescope eyepiece comes with protective lens and barrel caps.

Best purchase I've ever made. Super high quality and excellent views. Save yourself the time and buy a set of these. I am going to buy one of each and get ride of all my other lenses. Completely satisfied and cannot wait to get out viewing again. Best lenses around for the money, seriously.

In all fairness, I am using a refractor the this eyepiece pushed beyond its limits. However, even with a magnification of close to 300x (useful is stated to be 240x), one could still clearly make out the bands of Jupiter as well as the red spot. The rings of Saturn were clear enough to easily see the Cassini division. For grins, I added a 2x barlow lens and pushed the magnification over 580x. Yes it was a bit fuzzy, but still viewable. When this eyepiece was placed into the 180mm Mak-Cass from Orion (770x), Saturn looked amazing.
This eyepiece definitely benefits from larger apertures. A 120mm refractor made things a bit dim but not bad. One could still make out the Ring nebula.
Pros: sharp clear views, solid feeling
Cons: a bit too much for smaller scopes

This was a great addition to my eyepiece line-up since I didn't have anything that approached this magnification. I'm using it with my Orion SkyQuest XT8 Classic Dobsonian Telescope which bring my magnification to 342x. This eyepiece offers a great design that magnifies the usual extremely small aperture of a high-powered eyepiece, which make using it much easier than cheaper eyepieces. Be warned though, this eyepiece will only produce decent images in ideal viewing conditions due to optical limitations.
Favorite viewing location:??My own backyard.
Favorite object to observe:??Jupiter
Yes, I recommend this product!
