I reshot the Bubble nebula last night using some different software. I didn't like how the software I've been using didn't have automatic focusing between filter changes. This new software is a lot more robust and automates almost everything.
When I was editing this new image, I also had an Ah-Ha moment. I've been editing all my astro photos the wrong way all this time! There is a function in stacking called "stretching" and I was stretching my images when I staked them, but also when I saved them later, essentially introducing a lot of noise and limiting detail needlessly. The stacking software automatically stretched images and it has to be deselected each time.
This is my first "correctly" edited image and I can see there is a lot less noise and a lot more detail.
Anyway, here is the image.
25, 300 second SII exposures
20, 300 second OIII exposures
20, 200 second Ha exposures
