Description

This was shot from a friends back yard in Canton GA, Bortle 5. I counted over 50 galaxies in this image, many of them being very faint (magnitude 16+) and I really had to push the data to pull them out of the background. I think that also accounts for the general lack of color, perhaps I should have shot more RGB and a bit less Lum.
