Any thoughts on the following would be welcome.
I spent today trying to process M101 RGB data (15 x 5mins each) using NSG (xnml version) and Mure Denoise. All seems ok except when I channel combine the colours seem washed out - noticeably there is virtually zero blue which is odd given M101 has a lot of blue details.
I then tried every combination of using/not using NSG and / or Mure and all of the tests worked except the ones using NSG.
So, NSG is causing the Blue to be lost from M101.
I suspect user error, else everyone would be complaining about this, but I have spent hours trying to find a problem including several reruns and it all looks ok.
Any thoughts why NSG, or my use of it, could be doing this?
