Explore Scientific AR102 Air-Spaced Doublet Refractor Telescope

Description The Explore Scientific AR Air-Spaced Doublet 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 apochromatic refractor, and you'll love the light weight of this instrument at only 11.5 lbs. 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-inch Two-Speed Crayford Focuser with Compression , a 99% Reflective Dielectric-Coated 2-inch Diagonal Mirror with 1.25-inch Eyepiece Adapter, the Explore Scientific Hybrid Finder Scope Base installed with an 8X50 non-illuminated straight-through finderscope and quick release bracket, and a cradle ring assembly with 45mm wide dovetail plate (Vixen style). Just add a few eyepieces and the alt-azimuth or equatorial mount of your choice and you’ll be ready to discover the Universe!
