Aluminum 102mm Doublet

Features The Explore Scientific AR Series telescopes are classic air-spaced, crown-and-flint, doublet achromatic f/6.5 refractors with a superior-class optical figure. Whether you choose the AR102 (4"), AR127 (5") or AR152 (6") model, you will be impressed by the stunning images revealed to you at the eyepiece, and all at a small fraction of the price you'd pay for a comparably sized apochromat refractor. Designed to handle the rigors of public star parties and educational outreach, the Explore Scientific AR Series telescopes come with heavy-duty, high quality components, including a 2" dual-speed focuser, a one-piece 2" diagonal with 99% dielectric coatings, an 8 X 50 non-illuminated straight -thru finderscope and quick release bracket, and a cradle ring assembly with Vixen-style dovetail mount. Just add a few eyepieces and the alt-azimuth or equatorial mount of your choice and you'll be ready to discover the Universe! Interferometic data on your newly purchased and registered Explore achromatic refractor is available upon request after 120 days of ownership. Please contact Customer Service for more information.
