Product Description
This is a good quality medium power fully-multicoated eyepiece at a very economical price for the astronomer on a budget. It's designed for lunar observing, for filling the eyepiece field with emission and reflection nebulas, for observing compact open clusters, and for sweeping nebular remnants. It will work well with any telescope type, at any focal ratio, under any seeing conditions. A soft rubber eyecup shields the eye from ambient light and folds down for eyeglass use. There will be some vignetting for those who must wear eyeglasses while observing. A knurled rubber ring on the titanium-colored barrel provides a secure grip when changing eyepieces in cold weather. Plastic caps are supplied to keep both ends of the eyepiece dust free.

I have been viewing for over 20 years and I have spent thousands of dollars on all sorts of eyepieces. Plossls are the eyepieces I use the most.
This Celestron plossl is nicer than the standard generic plossl, at least in 15 mm. The reason is that the diameter of the eye lens on this 15 mm is 5/8 inch, the same diameter as generic 20 mm plossl. As you know, as the focal length of the plossl gets smaller, the eye lens diameter gets smaller. On a generic 15 mm plossl the eye lens diameter is 7/16 inch. I will need to purchase more Celestron Omni eyepieces in other focal lengths to see if this trend continues in other focal lengths.
As far as viewing is concerned: This eye piece performs just fine, no complaints. I use generic plossls for bino viewing with a Denkmeier Bino Tron 27 and also with the older Deep Sky Viewer model, both are used with a power switch. I mostly use 32 mm focal length. I also have 32 mm eye pieces from Denkmeier which cost much more than Celestron Omni, there is no difference.
My telescopes: Celestron Nexstar 11 and a Takahashi Sky 90.
As a recommendation to viewers for eye piece purchasing: I have found out that your best bet is to purchase plossl down to about 9 mm focal length. These can also be used for bino viewing. Below 9 mm focal length, purchase the Pentax eye pieces. However, the Pentax eye pieces are suitable for bino viewing. Also it is nice to have a 40 mm focal length 2 inch eye piece with a 70 degree field of view.
