The Sky-Watcher STAR DISCOVERY 90i has been designed to be controlled wirelessly with your Smartphone or Tablet, using the free SynScan App for iOS or Android. The supplied Synscan Wi-Fi module creates it's very own Wi-Fi network, so the mount can be used anywhere, without any reliance on other WiFi or mobile networks. After entering your coordinates into the App and following a simple alignment procedure, you are ready to explore the universe using the App's intuitive touchscreen menu.
The STAR DISCOVERY 90i and SynScan App provides full computerised GO-TO control, allowing the telescope to be automatically slewed to any one of the objects in the App’s extensive database of 10,000+ celestial objects. Incorporates Sky-Watcher's Freedom-Find patented Dual-Encoder Technology, which allows the telescope to be moved manually in either axis without the mount losing its positional information. This gives the user enormous freedom, convenience and flexibility during observational sessions.
The Sky-Watcher STAR DISCOVERY 90i is a classic two-element, air-spaced, achromatic refractor. The telescope is easy to transport, and with its long focal length it is ideal for the detailed high-power study of the Moon, Planetary Surfaces and other objects in our solar system, providing crisp contrasty images. When combined with a Sky-Watcher 1.25" Erecting prism (code SW_20376, available separately) the telescope can be used during the day for high power terrestrial observations.
