      I use sextractor and imwcs all the time, in an automated fashion for
      my drift scan images.
      Both work really well. If you have a fairly good idea of the wcs, the
      imwcs works great. It requires
      an external catalogue, such as USNO, and will go out and get the
      appropriate section from an
      internet source. I have it on my computer which makes it much faster.

      Good luck,
