Questions & Answers

Shopper : Why Did You Choose This?ALLEN R : I already own the 10mm 1.25 inch and the 19mm 2-inch eyepieces. They are both great and I want higher magnifications for planets and DSO. I am confident that this lens will be an excellant performer with my 9.25-inch Edge HD scope. I also own the Celestron Regal M2 spotting scope which I like to set up when I am too lazy or do not have the time to set up the 9.25-inch scope. With the 7mm Luminos eyepiece coupled with that spotting scope I will get 77x magnification, great for moon and DSO's.ALLEN R : I purchased this for my Celestron 9.25 inch Edge HD SCT scope. I wanted a high-power eyepiece for planetary and DSO viewing. I already own the 10mm 1.25 inch and the 19mm 2-inch eyepiece and they give great images so I know the 7mm will perform well and the price is very reasonable. Additionally, I like the idea that the eyepieces are parfocal.MARK T : For telescopePABLO A : great reviews and recommendation for my type of telescopeDon S : Hard to find anywhere elseYuryi V : I like this seriesGEORGE S : Purchased to replace a Celestron X-Cel 7MM eyepiece that has a smaller FOV and I like trying different products. I use several different brands and types of optical lenses just to make it fun.

Luminos For the Win

I have several nice eyepieces. This Luminos 15mm give bright crisp views and the field of view is incredible. FOV is comparable to a 25mm at 65 degree. Will end up with more of this line.

Pleased with Luminos 10mm Eyepiece

The eyepiece works great. The eyepiece provides clarity, and a wide field of view that makes viewing feel like an immersion experience. Adorama provided excellent service at a competitive price.

Solid Eyepiece

Solid eyepiece as in good views. Solid eyepiece as in heavy weight. The 82 degree view is very nice. Feels like looking out of a picture window. Used with an OG C8 and an f6.6 refractor that are both fairly forgiving so I can't comment on any abberations that might come with faster scopes, but I didn't notice any in moon or star views. No easy planets to check out for me at this time. Very sharp image until extreme edges. Weighs a good bit so it did make my refractor focus lock do work.

Celestron Luminous 2.5X Barkow

This unit is solid!! It is a well made and reliable unit. It can also hold 2? as well as 1.25? eyepieces. The only draw back (but not really a con) is that the unit is slightly heavier than the X-Cel 1.25? Barlow making the tail of your image train slightly heavier and something that you need to ensure you plan and prepare for with a proper balance.

Celestron Luminous 31mm Lens

High quality glass!! Well built and sturdy! It does take a few minutes to get acclimated to this lens and find your proper eye relief. Once accomplished, images are well defined, sharp and clear! 31mm lens is quite big and heavy, so have the proper diagonal to accommodate it!

I purchased the Luminos 31mm and 10mm. I am quite pleased with them. I know the brand doesn't get high grades, but I like them. Adorama got them to me quickly too.

Celestron Luminos 31mm Really Delivers

I?ve had the 31mm for over a year. It delivers fantastic views in my 12? F6 dobsonian. As everyone who has one knows, this eyepiece is huge. Definitely overbuilt, but Celestron hit it out of the park with this one. For $280, it?s more than half the price off of the ?premium? competitors. The Luminos is Celestron?s premium line of eyepieces, and considered the best bang for the buck (similar to Meade?s UWAs). The sky is literally full of stars with the 31mm, especially at a dark site. I enjoy sweeping around just to look for anything that?s interesting. I?m not crazy about the 19mm due to the EOFB, but this 31mm is a bit better corrected which makes a noticeable difference. For high power planetary work, the 7mm performs well enough to observe Saturn?s Encke gap in detail. I?m saving up for the 10mm.

Aberrations are well corrected from center to corner even with fast newtonian reflectors (f/5). With f/4 the corner will suffer aberations.

Nice Eyepiece

I like it, it gives excellent, crisp views. I really like the retractable eye cups. It is a little bit on the heavy side. When used on my small 8" dob mount scope (a mount that is very sensitive for smooth movement) I have to add some counterweight to the business end to maintain balance. That is not an issue with my big heavy, sticky 13.1" dob scope, wind hardly registers on that scope. I have yet to try it on my 10" equatorial mounted Schmidt Newtonian I would recommend this eyepiece, just be ready for the weight.

Great Optics and Quality Construction

I purchased the Celestron Luminos 2.5x, 2" Barlow Lens to extend the focal length of a 10" Newtonian telescope for astrophotography. I have also use it for visual observation with long eye relief lenses to give me higher magnification with long eye relief. I am quite happy with the lens quality and the assembly construction. I'll be looking at Celestron Luminos products in the future.

Big View Eyepiece

By MIKE R.

The Celestron Luminos 10mm, 1.25 is a powerful, big view eyepiece. Coupled with my Explore Scientific Dobson 12" f5 telescope it's like you are in orbit around the moon. Mountains, craters, cool lava fields and all features are clearly visible. The image is sharp all across the huge 84 degree field of view. At 155x, though the viewing circle is huge, only about one quarter of the moon may be seen without scanning. Of the minimal distortion, most of it by far originates in the Earth's atmo...
