Not much difference between this and the supplied 25mm Celestron 8SE, but it can make a difference. Was able to capture the entire FOV for the double double, which was very impressive. Great for DSO and very faint light. Price is right and very fine EP

Love this eyepiece, lens quality is great definitely better than the ones my scope came with, easy to install and use, the lens is large in size and heavy, would recommend if using lenses provided with celestron’s scope.

Fantastic quality, great magnification and crisp details of planets.

A solid, well built eyepiece, that does not show not any chipping “paint” when repeatedly tightening the DIY holding screw of my DIY Crayford – in slightly different places.If you need something light, go for a Plössl, because this baby weighs in at a respectable 7.3 oz / 207 g, which is about half of the weight of the camera I’m using with my 6″ Dob.I have yet to test it extensively, but at first sight (moon viewing) it is free of distortions, obvious chromatic aberrations and sharp as a pin.It’s long focal length and a fairly wide Apparent FoV of 60º makes it an ideal companion for low-end telescopes (from ± 4 to 8″), for viewing planets and general deep sky objects.It is also a fairly priced (USD 65 + shipping / taxes) quality replacement for the crappy eyepieces that typically ship with entry level scopes.Although it’s 16mm eye relief eye cup is supposed to be a boon for eyeglass wearers, I have foud that I’m better off keeping it all the way down. Of course, your experience may be different.Still, it is good to know it is there, because in many eyepieces the relief may be a magnitude smaller or virtually non existent.Last but not least, the X-Cell series is supposed to be parfocal, although I have yet to prove this, which means that you can swap out any eyepiece without having to refocus.In conclusion.To me, the 25mm focal length is to a smallish scope what a 50mm lens is to a SLR camera: the one you start out with and – most likely – the only one that may not be amiss in most anybody’s bag.Although most likely not at the top of it’s class, the Celestron X-Cel 25mm is good and akin to a 50mm f/1.8 lens: a well-proven quality optical design in combination with a lot of bang for your buck.Given the positive experience with this eyepiece, I will soon aquire a shorter focal length from the same series (likely 9mm) in the hope that it will perform as well as this one.

This product is very popular and I see why now. I love the sturdiness and durability of the eyepiece! And of course the quality of views. This is my mostly used eyepiece with or without Barlow…. The adjustable eye up allowed me to take photos aswell with my phone and it looks even better to the naked eye… check out the photo of orions nebula I captured using my iPhone 13!

Ever since I tried one of these eye pieces, I wanted to get one to test it on my new dobsonian telescope. This thing does not dissapoint. I have used better and worse for sure, but x-cel lx is by FAR the most bang for your money.The eye relief is incredible, very comfortable. Compared to an UWA eye piece, this one is a lot more clear, no chromatic aberration and almost almost perfect flat field to the end. The FOV is aboutm60% and it is usable, even close to the edges. The construction is rock solid and the twist up eye guard is a great addition. What I like the most is that if you switch between X/CEL eyepieces, you do not need to refocus, if any. I now have the 25mm, 9mm and 2x Barlow, highly highly recommended product line.
