    Explore Scientific 102mm f/6.5 Doublet Refractor w/ EXOS-2 GoTo EQ Mount

    The classic air-spaced, crown-and-flint, doublet achromatic refractor has been resurrected with the goal of producing top-of-the-line optics in a short focal length design with Explore Scientific's Doublet AR series. Whichever AR model you choose, you will be thoroughly impressed by the image quality it yields at only a fraction of the cost of a similarly sized apochromatic refractor telescope.

    Created to hold up under the burden of public star parties and educational outreach, the Explore Scientific AR102 features heavy-duty, superior quality accessories, including a 2" dual-speed Crayford focuser, 2" diagonal with 99% dielectric coatings, 8x50 straight finderscope and bracket, and tube rings with Vixen-style dovetail. All you need are a few eyepieces and you'll be ready to explore the heavens!
