The premium 4-element apochromatic optics are fully multi-coated for optimum light transmission and yield high contrast, true color images.\u003cbr\u003e\u003cbr\u003eThe 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.\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.
