The ATS/STS 80 (HD) observation telescopes set the highest standards among telescopes in this category.
Even with the easy-to-handle fully rubberized armouring, the ATA/STS 80 (HD) are by far the lightest of
the larger observation telescopes. Thanks to a recalculated optical system, they offer a precise
observation of detail, optimum edge-to-edge images and almost 100 per cent colour fidelity with an
extremely wide field of view, thereby achieving a revolutionary image quality.
OPTICS:
* Extremely high-quality optical system for totally natural colour reproduction and precision
observation of detail, even when light conditions are poor
* HD (High Definition) instruments helps to eradicate the slightest chromatic zonal aberrations
and contributes to a more faithful colour image.
FOCUSING:
* Extremely short close focusing down to only 16 ft
(5 m).
* Easy-grip ergonomically positioned focusing ring with larger grooves for quick and precise
focusing.
USABILITY:
* Removable aid for quick target pick-up.
* Integrate objective lens protection. Stops glare and diffused light as well as protecting
against rain and snow. Lock mechanism in ultimate extended position: cannot move on its own and silent
to handle.
* Automatic safeguard against accidental unscrewing of the eyepieces.
* Full field of view even for spectacle wearers due to individually adjustable twist-in eyecups.
* Fast and easy mounting on Swarovski tripods without additional plate (standardised foot). Fits
also all Tripods with 1/4" and 3/8" threads.
* Large and easy-to-operate focusing ring even with gloves on.
* Easily removable lens cap.
* Compact and fits easily in hand-luggage.
ROBUSTNESS:
* Extremely light, but very sturdy light alloy housing.
* The fully rubberised armouring for shock absorption and noise reduction is easy to handle even
in cold weather.
* Internal focusing for dustproof and watertight qualities (up to a depth of 13 ft or 4 m).
* Full objective lens protection and objective lens thread for screw-in filters.
WEIGHT:
* Very light weight for ATS 80 (HD) of only 1300 g/45.9 oz (1350 g/47.6 oz) and for STS (HD) of
only 1280 g/45.2 oz (1330 g/46.9 oz). By far the lightest of the larger observation telescopes
