NGC 7635, the Bubble nebula is center left adjacent to the Messier 52 star cluster .
The rest of the image are giant Gas clouds. The “bubble” which looks tiny is 7 light years across or about 7000 times the size of our solar system.

Technical Details
Imaged over 3 nights (8 hours total) in my back yard in Portland Oregon with a Williams 71 scope and an asi294 color camera.
EQM mount and Radian Triad filter.
Stack in Astropixel, PP in Pixinsight, Capture, Affinity and Photoshop.
Another beautiful image, Dan! The Bubble nebula is pretty cool. It seems as if it has boiled up out of that fiery inferno. I like all the background stats too.
How many images comprise the 8 hour total time? Impressive stacking by that software.
Stunning photo Dan. I think what I like most about it is the subtle dust clouds that surround the main nebulas. You work has really got me excited to explore this genre.
Thanks Mark,
48-10 minute image stack. 10 minutes is kind of a sweet spot for me. I use a 120mm guide scope to micro manage the mount so I could shoot as long as is practical. I have shot as long as 20 minute exposures with sharp stars except you risk Elon Musk satellites messing with 20 minutes of time or other issues that pop up so 5-10 minute except for a few bright objects is the standard.
Long exposures stack fast also. Only 48 images to stack is 8 hours.
Fascinating structure here with great detail. The color is bold but doesn’t appear overdone. I always have to chuckle at what astronomers consider a wide field. Satellites and airplanes are an increasing frustration.
