Description:This Celestron Omni is a good quality medium power eyepiece at a good low price. It’s designed for detailed lunar observing, for getting up close and personal with emission and reflection nebulas, and for resolving globular clusters. It will work well with any telescope type, at any focal ratio, under virtually any seeing conditions. A soft rubber eyecup on the titanium-colored body shields the eye from ambient light and folds down for more comfortable eyeglass use.

The major issue with the 12mm may be eye relief, but it is OK for me and you will probably not need glasses with the small exit pupil it provides, even with an f/4.5 Dob. You can see the entire field stop if you press against the rubber eyecup. I would not go any shorter in FL in the Omni series. The optical performance is quite good and mine works quite well in an f/4 Stellarvue finder scope. A shorty Barlow will get you some more eye relief. The Omni series is a cheap route for binoviewer pairs. The prisms in cheap Chinese binoviewers will render more expensive EP's as probably a waste of money as sharpness will be limited by the binoviewer.

The 32mm and 25mm are the best of the Plossl line. Bright images, decent field of view, and good eye relief. When you drop below 25mm, the eye relief starts to get a little short. Below 10mm the eye relief is negligable - to the point where I won't use them even if I won them.
