Sky-Watcher Evolux 62mm ED Doublet Apo Refractor Telescope (NEW)

Building on the foundation of the popular Evostar line of refractors, Sky-Watcher has developed the all new Evolux 62ED Doublet Apo Refractor # S11305.  Designed for the savvy astrophotographer looking for a lightweight scope that still packs a punch with key upgrades in the optics and the mechanics, Evolux is a perfect fit for a widefield grab and go setup.

Sky-Watcher’s Evolux apochromatic doublet 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 our 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.

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, and adjustable dew shield. Optional reducer/corrector sold separerately (item # S20206).
