NGC 7635 the Bubble nebula

NGC 7635 the Bubble nebula

NGC 7538, the Bubble nebula, is an HII Emission nebula in the constellation of Cassiopeia around 7,100 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
