A zoom lens will not give anywhere near as good result as a prime lens and shooting wide open is not usually a good idea with faster primes. In both cases you will notice "blobby" stars though you will decrease the chance of star trails (if shooting un-guided) if shooting at maximum aperture.
Hope this helps.

The zeiss 21 and the canon 14 have pretty much nil distortion in my experience.
