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).
