Available in three apertures ranging from a highly portable 102 mm to a far-reaching 152mm, our AR Doublet Series telescopes are classic f/6.5 achromatic refractors that use a pairing of a crown glass lens and a flint glass lens separated by a cushion of air to minimize chromatic aberrations. The superior optical glass is fully multi-coated, and each model comes with a 2" dual-speed focuser, a one-piece 2" diagonal with 99% dielectric coatings, an 8 X 50 non-illuminated straight -thru finderscope and a cradle ring assembly with a Vixen-style dovetail mount. |
