Outline
The Opticstar AR80S Gold Dual Speed short-tube refractor is ideal as a portable scope and can be used for observing, imaging or as a guide scope. It uses a 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 dual speed 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 (f5) Gold Dual Speed refractor features a smooth dual speed Crayford focuser with a 2" drawtube (with 1.25” adapter), retractable metal dew shield

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.
