It just occurred to me that trial and error for the foreground painting may not require 45 minutes per shot at all... Can you just open the shutter, experiment with painting times/angles (2-3 minutes?), then check the exposure? At that point, the star trails will not have had time to develop, but you will at least have a baseline to work with during the longer exposure.
Thanks,
Bill
