Bubble nebula

Same spot, taken on 10/30.
Total exposure 1h25min, 17 x 5min, Canon 20Da, ISO 1600. The telescope was a Celestron 9.25, F=1480mm, f/6.3. I lost a few frames because of a shift in focus probably due to a lower temperature. Same method of guiding, same processing.

Thanks for looking!

Super job. I'm sure those of us who have tried this with a DSLR know how difficult it is to do the bubble properly.
