My attempt at capturing Comet SWAN, taken today between 5:30 to sunrise at 6:05. As i have a mono camera, i tried to capture as much data as i could in the very little time i had, so i only took about 20 images of 1 minute each using the luminance filter.

I also took some color data, but comet processing is very different from normal processing. So for now, i only have this luminance image, that allows to see some details in the tail.
