Description

I have been learning the fundamentals of image processing and now I am trying to get a grip on noise reduction. This image of LBN581 is a stack of 60x120s Ha subs taken with my ASI1600 and Baader filter. There are probably several things wrong with this image, but my concern now is the noise. I have been trying with “MultiscalelinearTransfor” a feel that I understand how it works, what other tools can I use? I would really like some feedback on the noise level and what I can do to reduce it.
