NGC7635 The Bubble Nebula HaOIIIRGB
NGC 7635, also known as the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.
32 hours of total integration. 57x1200s Ha, 30x1200s OIII, 10x300s Red, 10x300s Green, 12x300s Blue
