Sky-Watcher Evostar 90/900 (AZ3)

The Sky-Watcher Evostar 90/900 is an easy-to-use and high-quality achromatic refractor that is suitable for beginners. It is well suited for observing the Moon and the planets. The Sky-Watcher Evostar 90/900 comes with a sturdy and easy-to-use AZ3 azimuthal mount.

Operating the AZ3 mount

This mount has controls for movement in altitude (up-down) and azimuth (left-right). Coarse azimuth movement is controlled by a locking knob located near the tripod head for left-right rotation. Loosen the knob to make large direction changes then lock it for fine adjustments. Coarse Altitude movement is controlled by a friction bolt. Use the micro-adjustment control cables to make small altitude and azimuth movements such as centering objects in view. The micro-adjustment controls have limited travel so it is best to centre them on their threads before making a coarse adjustment.
