Celestron X-Cel Series Telescope Eyepieces

Comments about Celestron X-Cel Series Telescope Eyepieces:

I purchased a 12.5mm and an 8mm for use with my Celestron 8se. I had owned some similarly priced brand name plossl's and the X-CEL's are far superior for viewing comfort. The large aperture eye lens coupled with the long eye relief is comparable to viewing a screen as opposed to squinting thru a peephole with your eye pressed up against the glass as is the case with Plossl's of these focal lengths. I did read some reviews elsewhere that had complaints of image degradation at the edge of the field but I am not finding that myself. So far I have used these to view globular star clusters, the lunar surface, Jupiter, and M42 (Orion Nebula) and judge them to be satisfactory for the price paid. Overall quality and construction (fit and finish) is perfect. I will be completing the set over time.

The 5mm X-Cel is the most powerful eyepiece lens that can be used for the Celestron Nexstar 4SE.

Any eyepiece with more power- like the 2.5 mm will be to powerful to use.

The quality is fantastic, Celestron gives you more "Bang for the Buck."

The X-Cel Eyepiece Series is one of the best. Go and get one and see for yourself!

I bought the 25mm and the 2.3mm. The good: good eye relief, wide field of view, sharp image, parfocal (somewhat). The bad: Kidney Beaning, Kidney Beaning, Kidney Beaning, and minor coma at the edge of fov. These are a step up from the cheap plossls that came with my scope because of the reasons listed. However, on my fast f/5 scope there is coma at the edge of fov, which is expected, and you have to line up your eye just right or you get annoying kidney beaning. As an eyeglass wearer I normally don't wear them while viewing, however I put them on to test the eye relief. The 25mm was great with the eyecups rolled down - I didn't have to press them against the eyepiece to get the whole fov. The 2.3mm however, with the eyeglass lens TOUCHING the eyepiece I was limited to about only 75% of the field of view. On my 130mm f/5 Newt the 2.3 was pushing my upper mag limit at 280X. However, under average viewing conditions in a moderately light-polluted area, Saturn was crisp with the ring shadow clearly visible. The moon was great with both eyepieces. With the 2.3 I even saw clearly defined rifts on the surface and craters were razor sharp even to the edge of the fov. For the budget-conscious person, these are definitely a step up from the budget plossls and a great value. That said, I'm going to spend a little more and step up to the Hyperions

even though this lens was higher quality than the ones i have the larger size of the lens causes the telescope to loss the located image and i have to refind the image in the scope. but good lens

I had to try this eyepiece and expected to not even get focus on my bigger scope as the total magnification exceeds 880x on my scope, with a listed usable average of 480x - which we know is also pushing it - and the planets cannot support this power as clearly as less power - but I knew by looking at the eyepiece it was possible it would work. The pinhole that would exist on a plossl at even 5mm is replaced here to be as large as a 25mm lens. At this size the view is tremendous - granted that the viewer must be straight on to the eyepiece as you will lose the image. But straight on, looking at the moon on a cloudy night, I saw the smallest of crators, crisp as could be, and even what the craters contained. My Meade 4.7 was not as clear, or even as wide - how can this be? Great optics!
