I’ve tryed my data using BTX on stretched images and I’ve not had any luck with it. Before the “new”version of NoiseX I was able to get some decent results but not with the newest version of that.

My experience has been using BTX work with it the way it was intended to be used, in the linear state.

Just my 2 cent is all.

- BXT on linear as one of the first few steps:
The actual intended way to use it by the author, for good reasons if you understand the technical details of deconvolution. Will slightly enhance by using existing displaced information in your image as long as you didn't manipulate them first, if your aim is to stay as close to scientifically accurate as possible and preserve real details.

- BXT on non-linear:
Again, as explained by the author, it may appear sharper to humans in some case, however, these sharp "details" are hallucinations and mostly don't really exist. Makes sense too if you understand the technical details of deconvolution. If that's what you're aiming for for artistic purpose, no one will stop you either.


Ignore comments I've seen implying that people follow general rules without understanding them like it's a religious thing. It brings nothing good to the conversation and only demonstrate their own ignorance on the subject. We do know why.

If you have time to watch it fully and understand the technical language, the author address most of your questions in this video: https://www.youtube.com/watch?v=6hkVBnYYlss

I never suggested that people follow the rules without understanding them.  Nor did anyone else in this thread.  I even offered information on why this particular rule should be followed.  I did suggest that people follow the rules if they don't understand them well enough to know why they might want to occasionally break them.  It's not like there's an astronomy cabal making up some rulebook to force on others.  These "rules" are actually best practices which will serve to use the collected wisdom of people who have done this for a long time and understand it well to get a jump start on processing images well.  So for people new to astrophotography I would say feel free to break the rules all you want.  Just don't be surprised when your results are poor and your images are not well received as a result.  If you want to achieve good results, learn what these best practices are, why they work, and then apply them.  In a few years when you look back at your earlier images you'll be glad you did.
