On the california it was background neutralization and color calibrated, then linked stf->histogramtransformation. On HOO lowers nebula it was seperate STF on Ha and OIII to histogramtranformation, then channel combination to HOO.
In my discussions with Bill Blanshan all that needs to be done is Background Neutralization and an unlinked stretch prior to Narrowband Normalization. If you run standard color calibration not SPCC than you can use a linked stretch or use GHS. Most of the time I find that BN, Star XT and Noise XT then Bills unlinked stretch work. There are situations where I use Color Calibration if I plan to use GHS. If you use SPCC it messes with the color which defeats the purpose of Narrowband Normalization.
I dont run spcc on narrowband. We are messing with the palette right off the bat anyways. In the SHO it was standard calibration and a linked stretch. Usually I dont color calibrate and do all channels seperately as oiii or sii is usually very weak and takes its own effort to bring up as well.
I have processed SHO using Channel Combination and an unlinked stretch. The only reason Bill Blanshan recommends Color Calibration is for those that want to use GHS. You mentioned that you are not have good results with the NN script with SHO which tells me that the workflow you are using is not correct.
The less than ideal results are around how much shadow is being stretched. Too much contrast in there. The colors look just fine. I will just run it in an unlinked stretch, but unlinked stretch is doing roughly what standard color calibration is doing anyways. Not all tools will be ideal for all objects as well.
Thank you very much for your very, very good scripts and your videos!!
Amazing. As I get into PixInsight, I realize there is so much more to processing images to make them stand out.
Fantastic tutorial. This is now my goto channel for all things PI. Many thanks.
Thanks so much! If you got specific questions or want to see something else covered just reach out!
great tutorial. thanks for sharing
Very helpful, thank you for sharing.
Wow! Thank you very much!
thanks very instructive.
Super 👍…merci à toi..!.
Before you used Narrowband Normalization did you use SPCC or a linked stretch?

Thanks. Please change The Music from your videos. It vecinos annoying. Thanks again
What would you suggest? Different style of background music or no background music at all?
@@setiv2 It's nice to have background music (sometimes) ... but , in my opinion , if it's always the same it "get`s in the way"...
