Product Description

Size Name: 9mm - 1.25 Inch Format

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 benefitfrom the features that make this series unique. The Omni is a 4 -element premium symmetrical Plossl optical design. Features include blackened lens edges to minimize internal reflection and maximize contrast, multi-layer coating group oneach 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.

3.0 out of 5 stars I wanted to like this eyepiece, August 7, 2010

I bought this eyepiece to use with my 4.5" f/8 Celestron telescope, but I also have a 10" f/4.7 Orion telescope. I have found that this eyepiece works well in the slower scope, where it gives bright, sharp images. However, it is not up to the task in my faster f/4.7 scope. In the faster scope the view is on the dim side and a lot less sharp. I wish I had bought a 32mm Orion Highlight eyepiece rather than this one.

This review is from: Omni Series Eyepiece 1 1/4" 40mm (Electronics)

I recently purchased my 1st telescope, a 5" reflector. The widest eye piece it came with was I think 20mm and the sighting device (star pointer I believe it is called) is very hard for me to use, perhaps thanks to being far sighted.

So I purchased this to get a wide view to have a better chance at finding what I'm looking for.

Wow, it has a super-wide and bright view. It feels well made. I don't know much about this stuff, but at the moment this is my favorite lens.

This review is from: Celestron Omni Series 1-1/4 4MM Eyepiece (Electronics)

It does what it is designed to do. It is a 4mm eyepiece of pretty good quality. I bought it for my 4.5" reflector telescope. My scope has a 1000mm focal length, so I was hoping for an awesome 250x magnification. Well I got the 250x magnification, but the image was not very awesome. Yea, I know, I exceeded the recommended magnification for my size scope, but I had to find out for myself. The image through my Celestron 10mm eyepiece that came with the scope is much better, and the Celestron 20mm eyepiece it came with better yet. This eyepiece may be better suited for a larger mirrored scope.
My main issue with this eyepiece is that it is uncomfortable to use. The eye relief is VERY short. I almost have to have my eyeball touching the lens to see the full field of view, and my eye so close that my eyelashes constantly press against the lens and get in the way. Not enjoyable.
