About SynScan
Use the SynScan app to control Sky-Watcher telescope mounts via Wi-Fi or Bluetooth LE. Mounts without built-in Wi-Fi can be supported via a SynScan Wi-Fi adapter.
This version of the SynScan app is suited for novice users using alt-azimuth mounts.
Features
- Control telescope mount to slew, align, GOTO and track.
- Point And Track: track celestial objects (including the Sun and planets) without aligning.
- Support gamepad navigation.
- Browse a catalog of stars, comets, and deep sky objects. Or, save your own objects.
- Provide access to mount for use by third-party apps, including ASCOM clients, SkySafari, Luminos, Stellarium Mobile Plus, Stellarium Desktop or customer-developed apps. Also set up mount alignment for Luminos, Skysafari.
- Support access to the mount and the SynScan app from any platform that supports TCP/UDP connections.
- Provide emulator mount for testing and practicing.
- Track fast-moving earth satellites by working with the PreviSat app on Windows PC or the Lumios app on iOS devices.
