For astronomers looking to elevate their viewing experience with superior extra-low dispersion glass, look no further than Sky-Watchers EvoStar series of apochromatic doublets. Whether youre viewing the Moon for the first time or a seasoned astronomer, savor one of the finest viewing experiences Sky-Watcher has to offer. The EvoStar ED refractor lens assembly utilizes a proprietary combination of matched lenses, designed to deliver optimum visual and photographic performance. Even when observing bright planetary objects, the EvoStar ED refractor minimizes color fringing to deliver an image with tack-sharp stars. Central to Sky-Watchers color correction is their Metallic High-Transmission Coatings (MHTC), which eliminates virtually all false color. All EvoStar ED refractor optical tubes have been light-baffled to minimize stray light, and the tube interior features a matte black finish to prevent light reflections from reaching the focal plane.For the visual astronomer looking to try their hand at astrophotography, the Sky-Watcher EvoStar ED refractor series provides the perfect pathway to professional-level imaging without the need for braking the bank. Doublets cost less to produce, making them considerably less expensive than triplets. Additionally, fewer lens elements means less glass, which means less weight. Less weight means you can handle your equipment with a less beefy thus less expensive mount. With these savings you can invest in a new camera or laptop to enhance your astrophotography.Like the optics, the tube is beautifully crafted featuring rolled steel with our Sky-Watcher signature Black Diamond metal-flake finish. To contrast, the front and rear cells are constructed with a textured off-white aluminum casting. Whether youre viewing from a home observatory or at an outreach event, the EvoStar ED refractor stands out amongst a crowded field of telescopes.Sky-Watcher EvoStar includes rings and a dovetail, giving you the perfect setup thats ready to go at a moments notice. The 2 dual-speed Crayford-style focuser provides precise focusing using roller bearings that provide minimal image shift. Our optical tubes are shipped with a foam-lined aluminum case to help transport your investment to and from star parties or any other field-based observation.
