Thanks Allan
That’s very helpful. I’ll have a look at that and see where that happened.

Hi Chris,
it can be avoided using the free program that I use:
NASA FITS Liberator.
https://esahubble.org/projects/fits_.../download_v30/
Take the stacked FITS file in and use the stretch function x^(1/5).
Move the sliders full left and right -
that will give you maximum compression so that all levels
are spread out evenly over the 255 possible bits when you finally
convert from Tiff to jpeg.
cheers
Allan
