code for AltAz telescopes (primarily Dobsonians) to utilise plate-solving to improve pointing accuracy.
Requires:
- Raspberry Pi (4 or 5) running Bookworm 64 bit OS
- A custom hand box (Raspberry Pi Pico, OLED display and switches) connected via USB
- A Nexus DSC with optical encoders, connected with a ttl to USB cable
- An ASI Camera (Suggest ASI120MM-S), with 50mm f1.8 or faster cctv lens

Note: As of September 2024 uart3 is used instead of uart0 on the Pi5. Old hardware builds will need to be modified (switch two pairs of wires on the GPIO)
eFinder26_4.py is the latest stable version. Adds support for Sitech drives. Adds new 2 star alignment process (same really - but new screens)
The handbox version will autostart on power up.
VNC and ssh is enabled at efinder.local
VNC can be used to run the Graphical Display variant by executing in a terminal window....
venv-efinder/bin/python ~/Solver/eFinderVNCGUI.py run
The 'run' argument at the end causes the autostart version (eFinder.py) to be killed
