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.\u003cbr\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAdditional Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe Celestron 2.5x Luminos Barlow increases the magnification of any 2” or 1.25” eyepiece by two and a half times\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eHigh-quality 4-element optics produce a flat field for sharp images that are free of extraneous color\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eHard-anodized aluminum barrel is threaded to accept 2” filters\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eA brass compression ring holds eyepieces firmly in place, and large thumbscrews are easy to turn, even with gloves on\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eA 2” to 1.25” adapter is included.

It has taken a good 15 years, but I think we’re finally laying to rest the popular myth of the “degrading Barlow.” In a 1997 Sky \u0026amp; Telescope review, Terrence Dickenson wrote “…Technology has erased the old objections. A modern Barlow will not degrade your telescope’s optics. Anyone telling you otherwise is using outdated information.

Add a Celestron Omni 2X Barlow Lens to the mix, and now you have four magnifications to choose from.

When you use a Barlow lens with an eyepiece, you get double the magnification, but the eye relief is not affected. This is a good thing, because normally the shorter the focal length of the eyepiece, the less eye relief you have. In other words, a standard 10mm eyepiece, as a general rule, will have better eye relief than a 5mm eyepiece. Bonus! \u003cbr\u003e\u003cbr\u003eThe Celestron Omni 2x Barlow comes in a sleek, silver package. The two-element optics are fully multi-coated, and the edges of the lenses are blackened to cut down on internal reflections.
