@khufkens For night time manual exposure control I’ve experimented with this LUX meter. It works great in daylight but not as well after the sun goes down. Because of that I tried a combination of the meter with sunset/sunrise timings to manually ramp the camera exposure to 15 or 20 seconds for star photos.
Here is the script I wrote. After a several month hiatus I started adding USB support last week but haven’t gotten to test it yet because I accidentally dropped my pi in the lake
@codetricity Check out my script for gps metadata injection via gpsd and a cheap usb gps device.
