i tried another stack just using my existing data and only 18 subs (tried 10 but felt the result wasn't as good maybe with lower ISO it will be)
have attached the original for comparison as well
I used my existing master calibration files 50 x Each darks, flats, bias,
so not sure if i should reduce the number of them as well
i also spent a bit more time on the processing
the result is a definite improvement, the cores are not as washed out.
thanks again for the help
I'm doing a few trips this year to dark sky locations (Bortle 1)
so will have another crack at this one with lower ISO settings

those are great images with a high bench mark
thanks
