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 killer5
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.
