Pi-LC-Autoguider
To work with RaspiOS based on BULLSEYE or BOOKWORM, using libcamera (NOT raspistill/raspivid). At your own risk !!. Ensure you have any required software backed up.
This script was developed using a Raspberry PI with libcamera to auto guide a telescope through a ST-4 port using a Raspberry Pi (Pi2B/Pi3B/Pi3B+/Pi4/Pi5 recommended) and a suitable interface.
For interface details etc see https://github.com/Gordon999/Pi-AutoGuider

To install:
Install latest RaspiOS based on Bullseye or BOOKWORM (tested with FULL 32bit and 64bit versions)
then...
for BUSTER & BULLSEYE but NOT BOOKWORM - python3 -m pip install -U pygame --user and sudo apt install libsdl2-ttf-2.0 and... sudo apt install libsdl-gfx1.2-5 libsdl-image1.2 libsdl-kitchensink1 libsdl-mixer1.2 libsdl-sound1.2 libsdl-ttf2.0-0 libsdl1.2debian libsdl2-2.0-0 libsdl2-gfx-1.0-0 libsdl2-image-2.0-0 libsdl2-mixer-2.0-0 libsdl2-ttf-2.0-0
then... if using BOOKWORM switch to X11, sudo raspi-config, advanced, option A6 and choose X11, reboot.
Download PiLCAG.py, copy to /home/USER and run it
The interface can be an opto-isolator, relay card available for the Pi, eg Seeed Raspberry PI card, PiFace Relay Plus card, Sainsmart USB 4 relay card or any 4 relay card you interface.
The relay cards can also be modified, different wiring to scope, to auto-guide other scopes eg Meade LX-10.
It can also be interfaced to scopes via an Arduino Uno or Pi Pico, via USB. The Arduino Uno or Pi Pico can also be controlled by a PC using software such as PHD. Details can be found under the Arduino-Uno-AutoGuider repository or https://github.com/Gordon999/RPi-Pico-Autoguider
The Pi can also control a Canon DSLR, via an interface, to allow long exposure photographs.
Sony A6000* can also be used for long exposure photographs and controlled by 3 methods...
*Note although A6000 is tested I have also tested on a A7R4 so should work on several Sony models. Note you can't use the Electronic shutter with BULB.
If you want to try your camera download my https://github.com/Gordon999/Pi-Sony-A6000-remote and try them. Connect an IR led to gpio pin number 36.
Modifying Sony RM-SPR1 remote button (See Sony.txt and related photos) with extra FOCUS control gpio added (pin 23). Use of Infra Red diode to a gpio and Sony RMT-VP1 receiver.. Use of Infra Red diode to a gpio directly to camera (limited camera battery life !!) Please take care when interfacing your telescope or camera. At your own risk.
