Here's my feeble attempt at the Bubble Nebula. Needless to say it only looks like a partial bubble. This is a total of 114 minutes of exposure at ISO 3200. I processed the raw images in DSS in Kappa-Sigma mode with 2x Drizzle enabled and I still only got a partial bubble. Any suggestions on getting the rest of the bubble to show up? I've never tried filters and don't know if that would help or not. Any suggestion is appreciated.
