working on stellar profiles in m17

hello all, with the weather the way it is in melbourne its a chance to up the processing skills.... this time its stellar profiles, hopefully this one has the goods. i want to have the stars so you can tell their colour and not just white dots. i found the line tool and ran it over the stars ... very informative, of course it helps if you know what you are doing so what ive aimed for is


not burnt out in the middle of the stars,
colour blending to a white point.

trying to tick the other boxes too

ie

non crunchy stars
color balance ok (?) i think so
histogram not clipped , sky value 20-30
detail in the nebulosity

i could have bumped up the saturation but for this experiment not nesccesary i think. note crop is 1:1 so would equate to a 30 inch x 20 inch print section.

so guinea pigs required constructive pointing allowed.
