From my light polluted front yard. This is a mix of an older shot from my AT6RC and a recent from my AT72ED. 95 percent of the image was 30 second exposures and the other 5 percent were 2 minute. There was no focal reducer on the 6RC. 30 second subs at f9.

All processing done in PixInsight.

Maybe this year I can revisit the Trifid with the AT6RC.
