Sky-Watcher Evostar ED100 Refractor with Hard Case, 2 Inch Diagonal, and Accessories (Pre-Owned)

The EvoStar 100mm f/9 Doublet APO Refractor from Sky-Watcher features a doublet apochromatic lens system with Extra-low Dispersion (ED) glass and Sky-Watcher's proprietary photon anti-rejection Metallic High-Transmission Coatings (MHC) on all air-to-glass optical surfaces. This combination of glass, lenses, and coatings virtually eliminates chromatic aberrations for clear and bright high-contrast images with true color rendition. This is a versatile optical tube assembly (OTA) that is well suited for wide-field astronomical observation of prominent nebulae, star clusters and galaxies, or can be used as an astrograph for sky photography, a terrestrial spotting scope or telephoto lens. The aperture of this 100mm model of the ProED not only increases image brightness over the smaller 80mm version, it improves resolution and contrast.

NOTE: THIS OPTICAL TUBE DOES NOT COME WITH CRADLE RINGS OR VIXEN DOVETAIL THESE ITEMS ARE AVAILABLE AT AN ADDITIONAL COST.

Its two-speed Crayford-style focuser helps make fine-focusing fast and precise without backlash. The EvoStar comes with several accessories to help you get observing faster and easier. First, are two long eye relief eyepieces that produce 30 and 120x magnification, a 90° star diagonal for more comfortable viewing, and a large 8x50 erect-image finderscope to make finding your celestial objects faster and easier. Finally, Sky-Watcher provides a foam-lined aluminum carrying case to safely store and transport the OTA.
