The Explore Scientific AR Series telescopes are classic doublet achromatic f/6.5 refractors designed to provide low and medium magnification, wide field views of the sky. 

The Explore Scientific AR Series telescopes include a 2" dual-speed Crayford-style 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.

A Twilight I mount is included. The Twilight I is a light-duty alt-azimuth mount and tripod designed to quickly and easily accept small to medium sized refractors.  Slow-motion control cables are attached on the vertical and horizontal axes, and are easy to turn during the night.
