M51 processing questions
Posted: Wed May 25, 2022 11:27 am
Hello,
I imaged M51 last night, and just processed it with Startools. I am new to using this software, and not very familiar with all of its functionality. The final image came out ok, with the exception of a bright halo/color bleeding from the smaller adjoined galaxy (NGC 5194). How can I get rid of that, and in general clean up the image? If it helps, I included google drive links to the image below (raw stack and final processed file).
Thanks!
