It’s galaxy season and this is my first time trying my skills at broadband targets from bortle 9 skies. I’ve always avoided them from urban areas for obvious reasons. Time being the main one but also my lack of knowledge with these types of targets in terms processing and getting reasonable results. So I was nervous but curious and also feeling up to the challenge. So, here it is. My first attempt and I’m pretty pleased. Especially since it’s only 6hrs of data. Any suggestions for improvements greatly appreciated. I’m here to learn.

I just posted this same image, love the blues you got in yours, mine is a lot more brown/red, I was shooting with just the UV/IR cut in bortle 8, gonna try and get some Ha/OIII data at some point. Good job!
Looks fantastic, especially for the time and bortle 9. Some good color with just a broadband filter.
Great capture! If you have the ability to take some Ha data (maybe a couple of hours), you could really enhance the M82 Ha jets. If you’ve not done it before, there are some YouTube vids that describe processes to add Ha data to LRGB. I use Continuum Subtraction. I’d be happy to give you a couple of PI processes I use if that would help.
