Explore Scientific AR127

859.95 $

The classic air-spaced, crown-and-flint, doublet achromatic refractor is reborn with the aim to produce superior-class optical figure in a short (f/6.5) focal length design with Explore Scientific Air-Spaced Doublet AR Series. These optics are an extreme value, produce stunning images of deep sky objects, double stars, planets, and the moon that are a small fraction of the price of comparable aperture apochromat refractors. Finally one can own a diffraction-limited high quality refractor for a relatively modest investment.

Designed to handle the rigors of public star parties and educational outreach, the Explore Scientific AR Series has standard hardware which includes a precision 10:1 two-speed focuser, a 2-inch diagonal, an 8×50 finder scope, and a case. You can be confident that the quality and construction of these telescopes will allow heavy use for many years and are backed with a transferrable Five Year USA Limited Warranty.
