Why rule out the 24?  It may have distortions that are not acceptable wide
open in terrestrial photography that won't matter in astro work.  The
converse is certainly true.  My next choice would be either a 21mm f/2 or
the 28mm f/2, depending on how much sky you are trying to capture.
Alternatively, you could consider the f/2.8 version of the 24mm and use a
faster film to compensate.  Perhaps for this application it is a reasonable
compromise.  Like any lens, it is not at its best wide open, but tests I
recall indicate it is better than its f/2 cousin wide open.
