The Sky-Watcher Heritage-90 Virtuoso Telescope is a computerised, auto-tracking, Maksutov-Cassegrain telescope. It is ideal for observing the Moon, planets and double-stars, and also can be used for high power daytime terrestrial viewing. This telescope provides a stable platform and will track night sky objects automatically once located. It can be slewed automatically in both axes, at five different speeds, via the mount\'s electronic keypad. This mount can be upgraded to GoTo by purchasing a Synscan AZ GoTo handset and cable, allowing 42,900+ night sky objects to be automatically found from its extensive database.
