Hello, I was messing around with Pixinsight ... trying new things and I have a few questions about the Contrast Background Noise Ratio Script. 1) Can you use it to "measure" or "estimate" how you are doing on SNR for your image? 2) Can someone explain to me what would be an ideal CNBR? I ran the script on one raw image, no processing just a Screen Transfer Stretch and come up with Median 2116.14, Contrast 36.13, Background Mean 2091.13, Background Noise 30.06 and a CBRN of 1.20 I attached a screenshot of the results and peeking out from behind is the raw image.
Thank Walter
