It multiplies the focal length, and the eye relief survives · review
Celestron's X-Cel LX 2x: a three-element apochromatic, fully multi-coated 1.25-inch Barlow with a brass compression ring, a rubber grip and a filter thread.
Most Barlows hold the eyepiece with one or two setscrews that press on a single point of its barrel. Celestron uses a brass compression ring just inside the top: turning the thumbscrew closes the ring evenly around the eyepiece. It holds firmly and leaves no marks, which matters with eyepieces costing more than the Barlow.
The optics are a three-element apochromatic design, fully multi-coated. Celestron describes the images as virtually free of false color. A triplet holds color correction better than a simple doublet, most visibly on fast telescopes and on bright planets.
On November 7, 2026 it sold at $99.99. Celestron’s Omni 2x cost $34.99 and its X-Cel LX 3x, same build, $89.90.
The barrel accepts standard 1.25-inch filters. A filter there works with every eyepiece put into the Barlow.
No camera thread and no length. Amazon’s item data gives 159 g (5.6 oz). Celestron states a 2-year US warranty.

On a fast telescope, or with eyepieces you care about, often yes: the apochromatic triplet controls false color better and the compression ring will not mark barrels. On a slow f/10 telescope used visually, the difference is small and the [Omni 2x](/reviews/barlow-lenses-celestron/) does the job.
Yes, it shares their black-and-orange housing, and its 2x factor pairs well with them: a 25 mm X-Cel LX becomes an effective 12.5 mm.
Yes. The barrel is threaded for standard 1.25 in filters, so one filter on the Barlow works with every eyepiece in it.
