Sky-Watcher's Evostar apochromatic doublet refractors are 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 dual-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.

Description

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

The Evostar 150ED comes in a foam-lined aluminum case with tube rings, and a V-style dovetail plate.
