Comment
Overall I am so happy with how the shot turned out, considering I used the DSLR instead of the good old quattro and ZWO setup. Living in a bortle 7 zone makes shooting broadband targets very difficult. I had a hard time processing that data but in the end the result is very satisfying, even tough I have a little bit of noise in the background which can be improved in the future.
