## Description

SynScan Pro is the Pro version of the SynScan app for Sky-Watcher telescope mounts. It supports control via Wi‑Fi or Bluetooth LE, including mounts without built‑in Wi‑Fi via a SynScan Wi‑Fi adapter. Expert users can slew, align, GOTO, and track with features like Point And Track and gamepad navigation. 

It provides access for third‑party apps (ASCOM clients, SkySafari, Stellarium, Stellarium Mobile Plus, and others) over TCP/UDP, includes a mount emulator for testing, supports polar alignment, shutter control, and autoguiding via ASCOM, plus tools like auto home, PPEC, and park. This extension targets advanced users working with equatorial mounts and collaborative workflows across platforms.

## Review summary

User feedback shows strong potential as a wireless control tool with SkySafari Pro when it works, but reliability is a major concern. Recurrent crashes, unstable connections, and inconsistent alignment undermine field use. Updates/OS compatibility can break functionality, and data content (like the comet database) can be missing or slow to load. A subset of users reports positive, stable performance and ease of use, but the majority note significant reliability issues that limit practical use.

### Pros

- Seamless wireless interface to telescope mounts with SkySafari Pro integration.
- Easy remote control that can be more convenient than using the hand controller.
- Supports multiple mounts and devices (iPhone/iPad) for control.
- Automatic location/setup makes alignment easier and reduces manual input.
- Works well for some users, offering a smooth experience when functioning correctly.

### Cons

- Frequent crashes and freezes during alignment or operation; overall instability.
- Intermittent connection issues with errors like 'no device found' and dropping connections.
- Unreliable alignment accuracy; targets are often off and reset functions fail.
- Updates and newer iOS versions sometimes break connectivity or introduce bugs (need for downgrades or fixes).
- Data/content issues such as missing comet entries after updates and slow/blank comet library loading.
