I have been experimenting with the GHT and it appears to be a very powerful tool but there is a problem when the image is translated into formats other than FITS. Here is a screenshot side by side of how an example image looks in Siril vs. when saved as tif, png or jpg:
It appears that the MIPS-LO parameter may be the culprit. It is around 0.27 and this is put into the FITS header as “MIPS-FLO” with the comment “lower visualization cutoff”. Maybe this isn’t taken into account when translating the image into other formats. If, on the other hand, this is just user error, I would like to understand what I’m doing wrong.
Also, the new symmetry point selection feature doesn’t work in 16 bit mode, and always sets the symmetry point to 1 regardless of the selection area.
