Im a big fan of my 200mm F/2.8L for the canon, though haven't tested it for astro work.. also the 135mm F/2L and the 100mm F/2.8L

The 135 is a great trade off between aperture and FL and stoping down that bit further than the other two 2.8 lenses means shorter exposures for equal depth images Can't be bad!
