  • A brass compression ring holds eyepieces firmly in place, and large thumbscrews are easy to turn, even with gloves on.
  • A 2" to 1.25" adapter is included. Allows the use of both 2" and 1.25" eyepieces.

DESCRIPTION

The Celestron 2" Luminos Barlow Lens increases the magnification of your 2" and 1.25" eyepieces by 2.5x. The premium 4-element apochromatic optics are fully multi-coated for optimum light transmission and yield high contrast, true color images.

The beautiful hard-anodized aluminum housing matches the eyepieces in the Celestron Luminos line. A centralized 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 oversized 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.

Customer Reviews (4.8 / 5 · 5 reviews)

Aurora N. ★★★★★

The four-element optics in this Barlow really deliver—Jupiter's bands were crisp and contrasty even at 2.5x with my 10mm eyepiece. Fits both 2" and 1.25" barrels, which saved me from buying a second accessory.

Victoria ★★★★★

Finally got this in my 2" diagonal and Jupiter at 200x was crystal clear with no edge distortion. The 4-element glass really does make a difference over cheaper barlows I've tried.

Jacob ★★★★★

I was worried about image quality when stacking Barlows, but the flat field from this 2.5x is genuinely impressive. It threads onto both my 2-inch and 1.25-inch eyepieces without any fuss.
