The Bubble Nebula, NGC 7635, Sharpless 162, or Caldwell 11, is an H II region emission nebula in the constellation Cassiopeia. I managed to capture 7 images before the clouds came rolling across to end the show. A lot more data required for a decent image but it's a start!
7 x 360 second lights at -10°C, 125 gain.
5 x darks, 20 flats, 20 dark flats.
