Sky Watcher Evostar 90 AZ3 Telescope

For clear, high-contrast views of the Moon and planets, the Sky-Watcher Evostar-90 (AZ3) brings together a 90mm achromatic refractor optical tube with a 900mm focal length and f/10 focal ratio. This manual alt-azimuth telescope pairs Sky-Watcher’s Evostar-90 with the AZ3 Deluxe mount, giving a straightforward setup for beginners while offering the specification needed for more serious astronomical viewing.

The two-element, air-spaced, multi-coated objective lens is matched with a long focal length that suits detailed high-power observation of lunar and planetary subjects. Supplied eyepieces provide x36 and x90 magnification, while the telescope’s highest practical power is stated as x180. A 6x30 finderscope, 45 erect image diagonal and aluminium tripod with accessory tray complete the package.
