Product Description
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.

The Plossl killer
By Richard Rowell
The 68 degree field of view slaughters your old Plossls. This 13mm has nearly the field of view my 25mm Plossl does through my 10" F4.7 Newtonian. I love the huge (20mm) eye relief and the eyecup included is quite comfortable also. The large (1.25") exit glass makes it super easy to position your eye, no futzing with trying to get precisely positioned like with some other (higher priced) eyepiece lines. I also like the huge 13MM printed on the side in white as even in very low light I can tell which Stratus I'm grabbing.For $ this is a very impressive eyepiece. My only complaint would be that if a very bright object (such as the moon) is just out of the field of view, you can see a "light shadow" from the bright object. I haven't found this to be a problem however as I don't try to look at objects right next to the moon for obvious reasons :-)Overall, highly recommended.

By Pintado10
I so enjoyed the other Orion Stratus Eyepieces (24, 21, and 17mm) that I added it to the collection. I use the EP with my C8-SGT (f10) scope when I'm viewing Uranus and Neptune. Its also very good when I 2X barlow to look at Jupiter. It's also great for viewing Globular Clusters!!I will use it when Mars and Saturn are within view.

By Lauren H. Robison
I may not be Edwin Hubble or Carl Sagan nor do I have the biggest and best scope in the world. But I do have a nice mid range scope in an Orion XT8 Dobsonian and this eyepiece along with the 13mm and the 8mm that I purchased are my favorites by far. Terrific field of view and very high quality. It may not be a Nagler but at a fraction of a Nagler price, it makes beautiful images in my eyes. Love it and highly recommend this. They are heavy by the way and just so you know, they are the same eyepieces as Baader Hyperions. Oh I also like the big mm numbers Orion has stenciled on the side of the eyepieces. Makes it much easier to see in the dark. Highly recommended.
