walking noise

Ray Hansen
in PixInsight
I spent some time going through the pixinsight M101 tutorial for LRGB + Ha processing using the sample data from Hellas-Sky. The sample data master lights had a surprisingly large amount of walking noise that I tried removing with pattern subtraction without much success. I'm not losing any sleep over this one but am just curious if anyone has come up with a good way to address this.

    Not really.
    If the correlations are the issue... you *can* do something...I am not saying it is great.
    You can use the noise generator to *add* a tiny bit of noise and randomize the pattern a bit. 
    You would need to do this at the lowest brightness levels (up to the brightest walking pattern).

    Like I said... not a brilliant idea.
