]I added another 12x5min of M45 yesterday waiting for the Rosette nebula to come into sight. With 44x5min it's become easier to separate the background from the faint parts of the nebulae. Wish you good luck and CS in Dallas!

I never knew downtown Frankfurt was so dark!

This is what I am getting from the city (Dallas, TX).



There is only one word for this:

Terrible!

I'm sure there is much more in your data than what is visible here. How many light frames did you collect and what exposure time did you use?

665 light frames, 30s each at ISO400, mean ADUs 45 out of 256 (8 bit range, but imaged RAW on Nikon D3300.
I wish there were more data, but I don't think so. Air pollution and light pollution are so bad, I can hardly see Polaris with my naked eye.
