Ok I just committed a solution, please test.

Hi Jasem,
Couldn't test it with stars - shot cloudy sky instead.
Everything was running on RPI with latest nightly updates.
Still think the MAX should be higher - this is to prevent blowing the whites in fits view.
Need clear sky to check.

8bit auto-stretch ON


8bit auto-stretch OFF


16bit auto-stretch ON


16bit auto-stretch OFF

So I ran a quick test on the new feature by opening an eclipse photo from last month. When the "Autostretch" feature is turned on, it looks all blown out just like my photos looked in KStars during the Eclipse


But with the "Autostretch" feature turned off, the Moon looks very nice like it did in PixInsight.

Rob, that's great, but I think we need to do something about number of decimal places here.

Max, all your images look fine and there is no information loss now nor clipping.

Yes, I agree, max 2 or 3 digits after the decimal

Hello,
Tried today with real stars. With Windows client. Looks much better!
However, Windows version looks differently from RPI.
In Windows client, when unstretched, image/histogram shows full scale from 0 to 2^16 (for 16bit image) - that is great.
In RPI it's clipped from the right.
How close the builds for windows and Linux in terms of updates are? I think my windows version is just a couple of days newer.
Thanks!
