While testing my guiding setup, I wound up shooting 3 series of this over two nights. I wondered what I would get if I tried combining them.
Finally, some color is coming out! My plan for the next good night is to try for 3 hours worth of exposure and see what I get.
This is kinda vignetted--I didn't shoot flats since I was only worried about guiding. Next time.
