The all new Sky-Watcher Evolux ED series of doublet apochromatic refractors offer an update of the company’s classic Evostar series with key upgrades in the optics and mechanics. Designed for the astrophotographers looking to complement their lightweight, widefield, grab-and-go imaging setup, Evolux is also well suited for visual astronomy as well.
The new Evolux 62ED and the Evolux 82ED refractors are the perfect blend of superior extra-low dispersion glass and affordability. The lens assembly utilizes a proprietary combination of matched lenses, delivering tack-sharp stars with charcoal-black, contrast-rich skies. All ED glass elements feature Sky-Watcher’s proprietary Metallic High-Transmission Coatings (MHTC), virtually eliminating all false color while the adjustable dew shield prevents stray light and condensation from affecting your photography.
The Evolux 62ED offers 82mm aperture and 530mm focal length with an available optional reducer/corrector (360mm at F/5.8). The Evolux 62ED offers 62mm aperture and 400mm focal length and is available with an optional reducer/corrector (360mm at F/5.8)
Each Sky-Watcher Evolux comes in a foam-lined aluminum case with a 2.4-inch dual-speed rack-and-pinion-style focuser, dual finderscope brackets, a V-style dovetail, clamshell ring, adjustable dew shield, and the optional reducer/corrector.
