Questions & Answers

Shopper : If this were a 35mm lens what would its power be?MICHAEL B : You would need to know the focal length of the telescope you are using. Divide that by 35 mm and that will be the power. For example if the focal length of the telescope was 700 mm then the power is 700 mm/35 mm = 20.ED C : Power depends on scopes focal length. But given the same focal length, a 35mm lense would provide about half the power of an 18mm lense. To obtain magnification power divide focal length by lense size. DAVID L : To answer this question, one must know the focal length of your telescope. For example, if you have a scope that has a focal length of 900 mm and you want to use an 18mm eyepiece, what will the magnification be? Use the following formula: 900mm/18mm = 50X magnification. Similarly, the 35 mm eyepiece will offer a magnification of 25X on this 900mm focal length scope. I hope this answers your question.Terry N : It depends on the focal length of your telescope. If it has a focal length of 2000mm, your power would be 57x (2000 divided by 35). The same eyepeice in an 800mm scope, would be 23x.
Shopper : Why Did You Choose This?CHARLES D : I have found that the Celestron X-Cel LX eyepieces, when compared to other mid-priced eyepieces on planets, provide images that are just a little bit sharper and display more detail. Cheers CWDGUILLERMO B : I have a different focal length of this same type of eyepiece. I really enjoy the eye relief and wide apparent field of view so much that it has become my favorite eyepiece and I wanted another.CHRISTOPHER S : I'm buying this 18 mm X-Cel because of so many good positive reviews I'm buying the 18 in particular because the common 25 is currently on backorder so I think the 18 will service Justice not only that but it's from a leading brand like Celestron whom products I have always trustedJames L : Eye reliefSUSAN U : recommended by a friend

Best Barlow I Own!!!!

Top notch quality! I already own a cheaper Celestron 2x Barlow and the difference is night and day. I was hesitant to spend this much more than ?discount? versions. But it?s true: you get what you pay for. And Adorama offered a smooth, easy transaction as always. My package was in the mailbox in a matter of days; just in time for my next outing!

Great Upgrade Eyepieces

I am very new to astronomy and telescopes. Purchased my first about a two months ago (Celestron Nextstar 130SLt). Purchased the 25mm, 12mm, and 7mm along with the 2X Barlow. The construction and quality of these X-Cell LX eyepieces in great. Definitely a huge improvement compared to the ones included with my telescope. Simple viewing is much easier. The eye relief is good and the adjustable eye cup is great for me as I wear glasses. Will probably add the 18mm soon. Great service as usual from Adorama

Good addition to eyepiece collection

I bought this eyepiece to go with a celestron 130mm reflector. I was surprised by the weight & size. The view is nice out to the edges. The image is crisp. A good step up from the kit eyepieces at a reasonable price.

This is not a review, I?ve been harassed for a review of this and other products without being given a reasonable amount of time to use them.

I?ve not even had a chance to use it, but sure? let me write this review for a chance to win. Side note, Amazon and other companies would get more reviews and definitely more honest reviews if they?d stop badgering the customer for a damn review via text and email every 20 minutes after the purchase has been made.

Great to have.

Nice construction. Feels sturdy and good quality. I have used this a couple of times on my Celestron 127SLT and with an eyepiece attached this was great to view Mars. While still somewhat a dot in the sky, it was a bit larger dot that just with the eyepiece. My main reason for purchasing was to use in with my DSLR for planetary imaging. However, I have not been able to get a good viewing like this but I don't believe it's the fault of the Barlow lens and rather user error. Still a great piece to have in my telescope tool box.

Barlow lens for my telescope

Purchased this Barlow lens to have a doubled magnification with my eyepieces. I chose this Barlow lens because you can use a 1.25“ filter directly on the Barlow lens. I like it.

Love this eyepiece!

I am in love with this eyepiece!!! The field of vision is so large and the 7mm is a great addition to my collection. The eyepiece is heavier but only because it is sturdier. The extra grip in the middle is handy too, I often grab the center of the eyepiece. While the XCel is pricier, I am not going to be buying other eyepieces from now on, this is definitely my new favorite.

I use this eyepiece with my 12" Dobsonian telescope. It provides great views of the planets. Images are clear with a wide view of field.

By Murali R.

Bought this one based on reviews and Celestron support person recommendation this one has more elements (lens) and hence superior to kit eye pieces. That is true. Used this on Celestron 90x series and difference is out of the world. My son was so delighted to see the Orion Nebula and those star dust clouds. This eye piece is really good, though it costed a third of the price of telescope. I am a photographer and always believe in getting great quality glass. Yes it may cost a bit more but mak...
