NGC 7635, the Bubble nebula
NGC 7635, the Bubble nebula, is an HII emission nebula in the constellation of Cassiopeia around 7100 to 11,000 light years from Earth. The bubble is created by intense radiation and stellar winds from nearby stars. This was collected over several nights this past month from my light polluted skies of central Florida.

Sorry to be pedantic, but that's NGC 7635.
NGC 7538 is close by, but out of frame in this shot.
Otherwise, nice acquisition and processing. Blue channel is a bit strong in the low frequency areas, but otherwise, I like it!
