Sky-Watcher Heritage-90 Virtuoso: The Compact Planetary Specialist<\/h2>\n

The Sky-Watcher Heritage-90 Cass is a Maksutov-Cassegrain with a 90 mm aperture and a long focal length of 1250 mm (f\/13.9) on the Virtuoso tracking mount. This combination is made for one thing: sharp, high-contrast images of the moon, planets, and double stars in a tube weighing just 1.5 kg. The closed tube is also virtually maintenance-free: collimation is rarely needed.<\/p>\n

What do you see through the Heritage 90 Cass?<\/h2>\n

The Moon is the main stage: craters, mountain ranges, and rilles are razor-sharp at 125x. Jupiter displays its cloud bands, Saturn its rings, and Venus its phases. This optics also clearly splits double stars. Deep-sky objects such as the Orion Nebula and the Pleiades are visible, but the narrow field of view of 1250 mm makes extensive nebulae less suitable: for those, shorter Heritage-Newtonian telescopes like the Heritage-130P<\/a> better suited.<\/p>\n

Virtuoso: Auto-tracking, expandable to GoTo<\/h2>\n

Once aimed, the mount holds the object with multiple tracking speeds. Freedom Find allows manual movement without losing alignment, and those who wish can later connect a SynScan GoTo hand controller for automatic searching of over 40,000 objects. The included 90-degree star diagonal provides a comfortable viewing angle, even for terrestrial observations like birds.<\/p>\n

This is how to get the most out of this telescope<\/h2>\n
