Sky Watcher Heritage 90 Virtuoso Telescope

Compact and easy to set up, the Sky-Watcher Heritage-90 Virtuoso brings computerised tracking to a highly portable Maksutov-Cassegrain telescope. With a 90mm aperture, 1250mm focal length and f/13. 88 focal ratio on a computerised alt-azimuth mount, it offers a stable platform for lunar, planetary and double-star observation, while also supporting high-power terrestrial viewing in daylight.

The Virtuoso mount tracks objects automatically once they have been located and can be slewed in both axes using the electronic keypad at five selectable speeds. Primary and secondary mirrors carry Radiant Aluminium Quartz coating with up to 94% reflectivity. The telescope can also be upgraded to GoTo with a SynScan AZ GoTo handset and cable available separately, and the telescope or mount can be attached to most prosumer tripods via a 3/8-inch thread.
