SYNSCAN APP USER’S MANUAL 2020-10-08 SynScan App is an application running on Android, iOS, and Windows, for controlling Sky-Watcher motorized telescope mount. Never use your telescope to look directly at the sun. Permanent eye damage will result. Use a proper solar filter firmly mounted on the front of the telescope for viewing the sun. When observing the sun, place a dust cap over your finderscope or remove it to protect you from accidental exposure. Never use an eyepiece-type solar filter and never use your telescope to project sunlight onto another surface, the internal heat build-up will damage the telescope optical elements. 2 TABLE OF
