This excellent, ultra-light, refractor telescope kit from Celestron™ and the National Park Service Foundation comes with a custom backpack so you can tote it to where you can actually see stars. Offers super-fast, no-tool set-up, and weighs just 16 oz.

A bright little flashlight with (8) super-bright white LEDs in a circle and a less-than-5mW red laser right in the middle. One click and it's a flashlight, another click and it's a laser pointer. (Note: flashlight and pointer can't be on at the same time.) Measures 4-3/8" long x 1-1/8" dia in assorted colors dark silver, red or blue aluminum with knurled grips at both ends. Lasts 30 hours on a set of new alkaline batteries (3 "AAA" heavy duty batteries included).

Paul, the guy with vision around here, calls these the binocs to get if you're stepping up your binocular game. From Celestron®, they're Nature DX Series 8 x 42 and lightweight at about 22 oz with BaK-4 prisms, fully multi-coated optics, twist-up eyecups, 7.4 degree angular field of view (FOV), 6.5 ft near focus, linear FOV of 388 feet at 1000 yards, 17.5mm eye relief, 5.2mm exit pupil for brighter images and phase-coated optics. They're completely waterproof and nitrogen-purged to prevent fogging and are "perfect for birding" per Paul. Measure an easy-to-handle 5.3" x 4.9" x 2" and come with a case, neckstrap and chamois.

Al Luebbers, our founder, collected glass. Not glass like you'd find on a knick-knack shelf, but optical glass. Lenses, prisms, reticles and filters, for example. Focus on the filters. Many of his filters came out of military surplus, and this is for-real stuff. We mean many are solid dyed optical glass, ground and polished to flatness standards that were probably excessive. Others are from the old days in photographic optics, and their standards were even tighter than your militaristic Uncle's. We've found that photographers, artists, and optical designers still have an occasional need for good glass filters, so we're making a list of some goodies. As always, don't be timid about calling for quotes on quantities. If we have 'em, we'll sell 'em. Just don't sell them back. Please!
