Wayne, you can find SExtractor here:

http://www.astromatic.net/software/sextractor

It's primarily geared towards finding astronomical on FITS - standard
images. NB that some searches will point you to terapix's website, this will
just take you on to astromatic.

I don't think there is a windows version, but I may be wrong.

Cheers,
 - Sean
