Description:This fully-multicoated Plössl is a good quality medium high to high power eyepiece at a sensibly low price. It’s designed for high magnification lunar and planetary observing, bringing out detail in the smaller planetary nebulas, and for resolving globular clusters. It will work well with any telescope type, at any focal ratio. It is especially well suited to Schmidt-Cassegrains, where it provides close to the 1mm exit pupil recommended for maximum sharpness in observing lunar and planetary details. A soft rubber eyecup on the titanium-colored body shields the eye from ambient light and folds down for more comfortable eyeglass use.

Eye relief is too short and eye lens is too small to make this a comfortable EP. The 12mm Omni has the shortest eye relief that I will tolerate, and that's only because I don't wear glasses. It does give fairly sharp views, so if you are mainly planetary and only interested in what's in the middle of the FOV, it can work fairly well at that task.

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.
