Sky-Watcher EvoStar 100ED APO Refractor

Manufacturer's Website

Description

The Sky-Watcher EvoStar 100ED APO Refractor is the perfect blend of superior extra-low dispersion glass and affordability. The Evostar refractor lens assembly utilizes a proprietary combination of matched lenses, delivering tack-sharp stars with charcoal-black, contrast-rich skies. All ED glass elements are fluorite-based and feature our proprietary Metallic High-Transmission Coatings (MHTC), virtually eliminating all false color, while triple-baffles prevent stray light from affecting your photography. Like the optics, the tube is beautifully crafted using aluminum and finished with a black diamond metal-flake finish.

Using a doublet refractor instead of a triplet has some advantages: less glass means less weight, less weight means a less expensive optic, so you can dedicate more money for your camera or laptop while benefiting from a lightweight astrophotography rig.

The Evostar 100ED comes in a foam-lined aluminum case fully loaded with accessories, including: 2-inch Crayford-style focuser, 2-inch dielectric diagonal, two 1.25-inch eyepieces (5mm and 25mm), an 8x50 right-angle finderscope, tube rings, and a V-style dovetail.
