I have been pulling my hair out on this image! Older data from January, but the processing of it has been super difficult. It's possible that my exposures needed to be longer. This is it, though. I am done! It's an okay result and the bubble is pretty clear.
The Bubble Nebula (NGC 7635) is a 7–10 light-year wide emission nebula in Cassiopeia, located ~7,100–11,000 light-years from Earth. It is a glowing, spherical shell of gas sculpted by intense solar winds from a massive, 4-million-year-old hot central star (SAO 20575)
Messier 52 (NGC 7654) is a rich, young open cluster in the Cassiopeia constellation, located approximately 4,600 to 5,000 light-years away. Discovered by Charles Messier in 1774, it contains about 200–600 stars, is around 35–160 million years old, and is often described as having a "V" or fan shape with a bright yellow star on its edge.
