Evostar 100EDX APO Doublet

An Elegant Balance of Value and Performance

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 internal baffle prevent stray light from affecting your photography. Like the optics, the tube is beautifully crafted using aluminum and finished with a white 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 telescope, so you can dedicate more money for your mount, camera, or accessories while benefiting from a lightweight astrophotography rig.

Sky-Watcher Evostar EDX refractors provide the finest images obtainable in their design class. These doublet refractors deliver dramatic, coal-black skies and faithful, contrast-rich views of planetary and deep-space phenomenon that are second to none. Sky-Watcher Evostar EDX refractors are the logical choice for the discriminating amateur astronomer looking for an investment in advanced instrumentation for exceptional viewing and astrophotography.

Evostars come in a foam-lined aluminum case with accessories, including: 2.8-inch Crayford-style focuser, tube rings, camera angle adjuster, thread-on dew shield, focuser adapter ring, spacer, 1.25 to 2-inch adapter, and a V-style dovetail.
