Hugin can certainly help you align frames perfectly prior to any other
processing with the GIMP.
If you want to get really serious about astrophotography, you might also
check out IRAF which I used when I was doing this stuff using large
telescopes (4m reflector).
Warning: IRAF is not for the faint of heart - the learning curve is
almost vertical! Read the tutorials.
