Outline
The Opticstar ED80S short-tube refractor is ideal as a portable scope and can be used for observing, imaging or as a guide scope. It uses a high quality 80mm apochromatic doublet that is fully broad-band multicoated to ensure maximum light transmission.
The ED80S uses the higher quality FPL53 Fluorite glass rather than the FPL52 or FPL51 types. FPL53 Fluorite glass suppresses chromatic aberration and is very well suited for short focal lengths unlike the FPL52 or FPL51 types. 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 type 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. This eliminates movement and ensures orthogonality.

Optional ES80S Gold Traveller. The ED80S refractor features a high quality precision 1:10 two-speed Crayford type focuser with a 2" drawtube (1.25" adapter included), retractable metal dew shield, finder scope saddle, broadband fully multi-coated optics and comes complete with a quality padded travel-case or alternatively with a hard aluminium re-enforced padded case.

With a focal length of 500mm (f/6.25) the ED80S is also very well suited for wide field astrophotography, guiding as well as for nature photography.

With a minimum total length of only 39cm and 80mm aperture the ED80S is the perfect travel scope. All you need to start using the ED80S is a photographic tripod, diagonal and eyepieces.

The ED80S Gold Traveller as a Spotting Scope

The telescope will focus down to 11 meters and with the addition of a 2 inch extension tube the ED80S will focus down to 6 meters. The included padded case can be carried over one’s shoulder and provides ample storage space for the ED80S and its accessories.
