Description
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 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. - 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.

Seems a good app apart from everything you set, footer padding, elevation limits, resets to default after a few days. Apart from that it works perfectly.

There is a known problem with this version of the app when used on phones running Android 11. If you go to the Sky watcher site, you can download the apk to get a version that works on Android 11. Personally, I really like this app and the way it works with my AZ GTi.

Excellent app. Been running it for about six months with absolutely no issues whatsoever. Loving it so much that I actually bought the paid version that I have been using it for almost two years now. Never once did it lost a signal, while being using it for almost 5 hours per night while doing astrophotography.

Garbage app that will not work at all on my Galaxy A7 tablet. Main screen flashes at startup and then disappears just as quickly. Shame on Pacific Telescope for having a useless POS app. Selling my scope since its Goto functions are now useless. Pathetic.

Doesn't open. Meant to be for alt-az sky watcher mount. App doesn't open just crashes. Tried the SynScan pro which is meant for eq mounts. That at least opens but most functions including the control pad don't work. Waste of space and of money for the mount. For a supposed "hot" product this is not good enough.

Brightest star alignment won't work. The mount won't move. So have to use North and level. Some of the stars for alignment where over 100° off what the app was pointing the scope. I can clearly see stars, that would be idea for alignment, but the app doesn't include them. Some are too low in the horizon to even use. I'm disappointed and considering going over to electron.

I can't get it to connect to my android phone, Samsung Galaxy s20 fe. It will connect to my ipad but not the item I need outside, my phone.
