Product Description
If you are looking to move up to a higher quality eyepiece the Omni series provides more enhanced features in a wider selection of focal lengths. Celestron designed this series with the finer points in mind so you, the user, can benefit from the features that make this series unique. The Omni is a 4-element premium symmetrical Plössl optical design. Features include blackened lens edges to minimize internal reflection and maximize contrast, multi-layer coating group on each lens surface to maximize light transmission and contrast, and each Omni goes through a two-step anodizing process to prevent reflection from the top eyepiece barrel, unlike most other manufactures who use reflective surfaces. Threaded barrels accept 1-1/4'' Celestron thread-in filters. 4mm Omni Eyepiece Focal Length (mm) 4 mm (0.16 in) Angular Field of View (deg) 52 ° Eye Relief (mm) 6 mm (0.24 in) Size 1.25 in (32 mm) Eyepiece Elements 4 6mm Omni Eyepiece Focal Length (mm) 6 mm (0.24 in) Angular Field of View (deg) 52 ° Eye Relief (mm) 5 mm (0.2 in) Size 1.25 in (32 mm) Eyepiece Elements 4 9mm Omni Eyepiece Focal Length (mm) 9 mm (0.35 in) Angular Field of View (deg) 52 ° Eye Relief (mm) 6 mm (0.24 in) Size 1.25 in (32 mm) Eyepiece Elements 4 12.5mm Omni Eyepiece Focal Length (mm) 12.5 mm (0.49 in) Angular Field of View (deg) 52 ° Eye Relief (mm) 8 mm (0.31 in) Size 1.25 in (32 mm) Eyepiece Elements 4 15mm Omni Eyepiece Focal Length (mm) 15 mm (0.59 in) Angular Field of View (deg) 52 ° Eye Relief (mm) 13 mm (0.51 in) Size 1.25 in (32 mm) Eyepiece Elements 4 32mm Omni Eyepiece Focal Length (mm) 32 mm (1.26 in) Angular Field of View (deg) 52 ° Eye Relief (mm) 22 mm (0.87 in) Size 1.

Decent for its price, lesson learnt - get the 32mm instead of the 40mm.
By Hari
I wanted the widest eyepiece I could afford that I could use with my Celestron Omni XLT 120 refractor. I purchased the 40mm version first before buying this thinking I will get the widest view because of the longer focal length. The 32mm eyepiece has an apparent field of view of 50 degrees whereas the 40mm has a 43 degree view. I had overlooked this but waited for both the eyepieces to arrive so that I can test it myself and compare them both in my scope which has a 1000mm focal length.
Both of them are pretty sharp but start getting slightly blurry towards the edges which is expected for eyepieces in this price range. The 32 mm has a slightly wider view than the 40mm. This might be because of the 1.25 inch format of the eyepieces which restricts wider views beyond a point. That's why it makes sense to go for 2 inch format eyepieces which have larger openings for wider field of views provided your focuser supports it. What I noticed was that the 32mm's slightly wider view was also slightly more magnified than the 40mms because shorter eyepiece focal length translates to more magnification.
I tested it in clear skies last week and the Pleiades cluster still doesn't fit into the field of view with the 32mm but it still provided bright crisp views almost to the edges. The star cluster just spills outside the field of view but note that my scopes focal length is 1000mm which is not a wide scope.
The finish and build of the eyepiece is very good and the rubber eye cap is excellent and very useful if you wear glasses like me. Even otherwise, it acts as a shield preventing stray light degrading your image. The eye relief is good as well.
The conclusion - the 32mm is a clear winner here and I don't understand why Celestron would even offer a 40mm version in 1.25 inch format. I am going to be returning the 40mm and I hope this experience helps others in making a decision if they are confused.

Celestron Omni Series is good for the price but...
By Brian Asdell
If you are upgrading your eyepiece collection DO YOUR RESEARCH! There is really nothing wrong with these eyepieces - they are well made and do the job well enough. Every astronomer has Plossl type eyepieces in their collection because they are good inexpensive EP's, but there are many kinds and differences. One thing to look for is Field of View, this is how wide of an area you will see through the EP - the wider the better. The Omni series is about 43-45 degrees but many other brands offer 50 to 55 degrees for only about $10-$15 more and it's worth the investment, otherwise you may end up spending more money in the long run trying to find the right eyepieces. You should also look for "eye-relief", that's the distance of your eye to the eyepiece required to see the whole field of view, again, the bigger the better. The more powerful the EP the less eye relief so you just have to accept that. Do internet searches for "Plossl eyepiece review" and plan ahead.

Very nice low power eyepiece.
By John DePetro
This is my go to eyepiece when I get my scope out. Nice wide field of view and very clear. The rubber cup keeps my eyeglasses from hitting the hard plastic. Good price, great value.
