I attach a picture of NASA FITS Liberator after I clicked on
Stretch function and you can see all the options to try.
I used to try many different options and just look at what it did.
If I wanted to bring out detail in dark areas I'd choose
the function x^(1/5).
Other times on bright nebulas , ArcSinH (x) stretch was good.
cheers

Thanks Allan,
I don’t expect you to comment on Startools AutoDev , just have a read ( if your interested) for your own information to understand how this particular stretch module works , it’s totally different from traditional non linear Histogram transformations.
Cheers
Martin
