Sky-Watcher Evostar 150ED - S11190
Highlights
- Doublet apochromatic optical design
- Two-element, air-spaced optical assembly minimizes false color
- 150mm aperture, 1200mm focal length, f/8 focal ratio
- 2-inch dual-speed Crayford-style focuser
- Aluminum tube coated with glossy, black diamond metal-flake finish
- Iincluded accessories: tube rings, V-style dovetail, and foam-lined aluminum case
Note: Does not include mount, eyepiece or diagonal.
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.
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.
