Q.U.A.R.C.S (QHYCCD Universal Astrophotographic Remote Capture System) is an open-source software kit that supports the full function of mobile remote capture via WIFI and computer remote capture via LAN. It includes the mount control, camera control, autoguiding, electric focuser control, and Stellarium skymap function.
TRITON GOTO
This app simplifies controlling your OnStep telescope. It integrates telescope operation, an interactive sky chart, alignment tools, and 3D visualization for observing and astrophotography. Ideal for both beginners and advanced users of DIY equatorial mounts.
- Interactive sky chart with one-tap GOTO
- Visual three-star and polar alignment assistance
- Real-time 3D telescope orientation model
- Comprehensive telescope controls (slewing, manual movement, tracking)
- Meridian flip and limit monitoring
- Coordinate synchronization and position calibration
