I have gotten a very nice range of star colors in several recent star trails, taken from our rural property in a semi-dark area on clear nights. I shoot them at ISO 200, 16-35 lens between 16 and 24, f/6.3, 3 minute exposures stacked.
I may not have time to check in till Monday evening -- I appreciate all the help and I'll keep reading your material!
