I have been testing with manual still images. I don't know what i'm doing really but i think i took with with a 5 second exposure. used the below line. Wondering if i made a mistake getting this camera.

libcamera-still -q 95 -o test.jpg --shutter 5000000 --gain 1 --awbgains 1,1

For the green, the color gains go from 0 to 32 so you likely need to increase them. Run

libcamera-still  -v -o test.jpg --shutter 5000000 --metadata meta.txt

and then upload meta.txt. It should list many of default values.

I also tried different gain settings from 1 to 32 and the image is still very green. any ideas?

I found a good balance with adding --awbgains 1.7,1.7. It could probably be refined more but it takes me 2 minutes just to get one shot.

Run grep libcamera-still /var/log/allsky.log | tail -1 and post the results. Usually if it takes a long time to get one shot the camera is trying to do auto exposure or auto gain or auto white balance, where it has to take several pictures.
