The AR80S Guidescope kit consists of the Opticstar AR80S telescope, set of collimating rings and Vixen-type dovetail to mount the telescope to standard mount saddles as found on the Meade, Sky-Watcher, Celestron, Vixen and other mounts.

The Opticstar AR80S Gold short-tube refractor is ideal as a portable scope and can be used for observing, imaging or as a guide scope. It uses an 80mm achromatic doublet that is fully broad-band multicoated to increase light transmission.

The optical tube greatly benefits from metal knife-edge baffles (not the plastic less effective step type) that prevent stray light outside the field of view from reaching the focal plane. Knife-edge baffles markedly increase image contrast.

The Crayford focuser, main tube and lens assembly are screwed into each other for maximum rigidity, no peripheral screws are used as they can compromise the rigidity of the telescope.

The AR80S Gold refractor features a smooth Crayford focuser with a 2” drawtube (with 1.25" adapter), retractable metal dew shield, CNC rings with 1/4" photo tripod threads, and broadband fully multi-coated optics.

With a focal length of 400mm (f/5) the AR80S is very well suited for wide field astrophotography, guiding as well as nature photography.

With a minimum total length of only 40cm and 80mm aperture the AR80S Gold is the perfect travel scope. All you need to start using the AR80S Gold is a photographic tripod, diagonal and eyepieces.
