The Sky-Watcher 82ED Evolux Doublet Refractor sports extra-low dispersion glass with high end coatings, a 2.4" focuser sturdy enough for imaging equipment, and a custom hard case!  Portable enough to travel, and light enough to grace most any alt-azimuth or equatorial mount, the Evolux 82ED is a great choice for day or night, photography or visual use.

While the Evolux 82ED weighs about a pound more than the Evolux 62ED, it still only weighs 6.5 pounds, making it reasonably portable.  One could also argue that an increase of 75% in light-gathering more than makes up for that extra pound of weight!

This ED refractor is perfect for travel (it comes with its own case) as well as grab-and-go observing and imaging in your own backyard.  Or simply attach your DSLR camera via an optional M48 T-ring to the sturdy 2.4" focuser for some daytime photography! With a special blend of extra-low dispersion glass and Sky-Watcher's proprietary Metallic High-Transmission Coatings, you'll experience sharp, high contrast images. On top of that, the optics in the Evolux 82ED Doublet are precision matched! All of these extra steps insure that your results will be virtually free from extraneous color!

The Evolux optical tube assembly is CNC machined of aluminum and is finished in classic white with black and Sky-Watcher green accents. It includes a retractable dew shield to help keep dew at bay and block stray light from striking the optics and lowering contrast. When the dew shield is retracted, the Sky-Watcher Evolux 82ED is just 16.4" long, and, with included accessories, weighs a mere 6.5 pounds.

The dual speed (11:1) 2.4" rack and pinion focuser is over-sized for better load capacity than most standard 2" focusers.

Accessories you will receive include a hard case to keep your Evolux safe during storage or travel, a 6" Vixen-style dovetail and a clamshell mounting system with dual finderscope brackets (finder sold separately).

Imagers will be happy to note that there is an optional 0.9X reducer/corrector available for the Evolux 82ED. Once installed, the effective focal length will shorten from 530 mm to 477 mm, and the focal ratio will go from f/6.45 to f/5.8. That means an increase in imaging speed by 24 percent while insuring a flat field across the entire imaging area of an APS-C camera!
