Description

NGC 7635, also known as the Bubble Nebula, Sharpless 162, or Caldwell 11, is an 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, SAO 20575. 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. It was discovered in 1787 by William Herschel.

This was a very challenging acquisition as the only window of opportunity was during a full moon. So I didn't waste the clear night and tested the limits of my narrowband imaging. I was not able to acquire all the frames that I want as the weather deteriorated near the end of the week and fall clouds have now set in, so I decided to process what I had.

Processing was a challenge, stretching out the data to leave the effects of the moon behind. I don't think I could get the bubble any sharper as my seeing and equipment limited the sharpness of the small central element, but I would love to try again in the future under better conditions.

Would love to here you thoughts!
