Series 4000 f/3.3 CCD Focal Reducer/Field Flattener: The revolutionary Meade f/3.3 CCD Focal Reducer converts the optical systems of f/10 Schmidt-Cassegrain telescopes to f/3.3 for ultrafast CCD imaging, and with increased edge of field resolution and color correction. Mounted in its threaded cell, the f/3.3 CCD Focal Reducer attaches to the rear cells of all Meade LX-Series Schmidt- Cassegrains (pp. 16 - 57) and to other Schmidt-Cassegrain brands as well and reduces CCD exposure times by up to 80%. The 3-element, 41mm clear-aperture optics are multicoated to maximize light transmission. Included with each f/3.3 CCD Focal Reducer is a Variable T-Adapter that allows a range of f/ratios between f/3 and f/5 on f/10 Schmidt-Cassegrains. The f/3.3 CCD Focal Reducer may be used with CCD imagers of any brand and chip dimensions and produces spectacular results. Note, however, that the f/3.3 unit is not recommended for use in either visual or photographic imaging applications.

Remington 870/870 Express Holographic Point Sight & Mount Combo New! Sun Opics USA P/N CD13-MDS & SM4812 Holographic weapon sights are becoming more and more popular for a good reason. Mainly because they give the shooter the ability to quickly lock on a target even if the shooters head position is not aligned with the sight. The laser reticle basically performs the same function as a laser sight except that the laser is projected on to the clear window and not on to the target itself. Another definite advantage is holographic sights can be used in the brightest of sunlight where as a conventional laser maybe hard to see on a target at long distances and bright sunlight. What seperates the Sun Optics USA Holographic Sight from all others in it's price range? It's precision ground hand polished fully multicoated High Definition Lens and the fact it's backed by a lifetime warranty for material and workmanship right here in the USA. Couple this great sight with the very popular Remington 870 Express saddle mount and you've got yourself a sure winner. (For more info on the Remington 870 Express saddle mount see our individual listing or visit our store at www.sbdglobaloptics.com THANKS)

The OIII narrowband filter isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light. The result is extreme contrast between the black sky background and the faint photons of OIII light needed for detailed views of the Veil, Ring, Dumbbell, Crescent and Orion nebulae, among other objects. Each filter has an ultra hard, vacuum-deposited coating carefully designed to block all of the visual spectrum ranging from 400 to 700 nm. This eliminates the un-natural colored halos surrounding bright stars common with O III filters of less sophisticated coating technology.
