About this app

Use the SynScan app to control Sky-Watcher telescope mounts via Wi-Fi, USB or Bluetooth LE. Mounts without built-in Wi-Fi can be supported via a SynScan Wi-Fi adapter.

This is the Pro version of the SynScan app and contains features suited for expert users using equatorial 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.
- 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.
- SynMatrix AutoAlign: use the smartphone camera to align the telescope automatically.
- Perform polar alignment with or without a polar scope.
- Control shutter release (SNAP) port to trigger an attached camera. (Requires mount with SNAP port and adapter cable that matches camera.)
- Use ASCOM to perform autoguiding on mounts that do not have autoguider (ST-4) port.
- Other mount controls: auto home, PPEC, park

App generally sucks. Recent update made it much more stable as it now doesn't send confusing commands to the mount, so that's great but it completely broke the deep space object catalog, I am unable to type the designation. Also the app crashes after typing a named star, going to and the trying to close the named stars window. Honestly I don't get how they got it this wrong. Also for some reason but I don't think it's the app's issue, the phone looses connection every once in a while

this is amazing and free - I just required a $100 wifi dongle. it is so much easier to use than the clunky handset and requires no cable. my friends who use it describe aligning as like a video game, which means they're more likely to join me on my scope. I'm looking forward to trying the image capture function which appears to be an intervalometer for the camera, controlled through the mount , which I've only just discovered. can't recommend this more highly !

Both the standard and Pro will not work on my upto date mobile. WHEN I open, there a quick flash of the screen opening and then it shuts down. Rather annoying, since this firm is not keeping up with technology, they should include a warning. I have however an older tablet, which does have this app on and is running. So Astronomers, don't throw away that old phone, keep it for synscan.
