Thanks Louie,

What did you think of my reply - am I correct?

When I sampled all the bright stars in Photoshop curves -
none reached the top of the curve so I assumed that I had not saturated
any of the pixels - I therefore expected the star colours to be there.
I also ran the recommended gain of 5% & offset of 100.
I just checked all the bright stars on the curves eyedropper function
& they all read 217 out of 255 gray scale.
I checked the same strength levels on a particular medium brightness star on an 4 original RAW frames & I got:
Red = 72
Green = 76
Blue = 70
Lum. = 150

I'll have to think about those results as that's telling me that the stars are actually white.
