Does anyone know of a way to stop pink cores in bright stars when doing MaskedStretch on a
Thanks

Hi Jim,
Thanks Graeme - same as with the correct magenta stars it left rather nasty aberrations.Graeme1858 wrote: ↑Thu Aug 05, 2021 8:10 am Would a tweak to the Hue Curve with a star mask in place do the job?
I'm just guessing too!

Thanks for that Steve. You are absolutely right, the stars showing pink were indeed saturated right from the raw data. So that's a lesson learned! I had gone back to linear for the HSV.STEVE333 wrote: ↑Thu Aug 05, 2021 3:45 pm Hi David - The real problem sounds like your stars are saturated, maybe even in the RAW frame. For the future it might help to use shorter exposures. Of course that means more images to handle.
I believe the HSV process needs to be applied when the image is still linear (before the MaskedStretch). If you did that then you have done everything correctly. Some bright stars are just hard to deal with!
Cheers - Steve
