      Thank you (all) for your comments.

      I've been working with Tom Bisque over the past few days. We are trying
      to figure out why Research | Insert WCS is not working for me with
      CCDSoft and The Sky6.

      I also downloaded the SBIG STV manual - interesting reading about the
      STV measures "seeing".

      the download section for the STV manual, on page 25 they explain the way
      it does it, but also send you to an appendix where the formulas and
      calculations are.

      there a way, by using images that I've taken, to measure the FWHM of a
      star in the image?
