Celestron Luminos 2.5x Barlow Lens

This Celestron Barlow lens increases the magnification of any 1.25 or 2 inch eyepiece by 2.5x, and makes a useful addition to your astro inventory. The 4-element multi-coated apochromatic optics are tuned to produce a flat field of view without light loss or false colour, and the lens is threaded to accept 2 inch filters. The finish is excellent and practical: A hard-anodised aluminium housing with rubber grip and practically-sized thumb-screws - easy to operate, even with cold fingers or while wearing gloves.

The Celestron Luminos 2.5x Barlow Lens

The beautiful hard-anodised aluminium housing matches the eyepieces in the Celestron Luminos line. A centralised rubber grip helps to keep your hands securely on the barrel, even when your fingers are cold or you are wearing gloves. A brass compression ring just inside the top of the Luminos 2.5x Barlow grabs your 2" eyepieces gently but firmly when you turn the over-sized thumbscrew. Once the thumbscrew has been secured in place, the brass ring keeps your eyepiece in the Barlow instead of relying on the tip of the thumbscrew itself, offering a better grip and protecting the barrel from scratches. A matching 2" to 1.25" adapter is included so that you can increase the magnification of all of your eyepieces, both 1.25" and 2", in this versatile Barlow lens.

The insert barrel of the Celestron Luminos 2.5x Barlow is threaded to accept 2" filters. This is a nice feature, because you can change eyepieces without removing and reattaching the filter each time.
