All, For some reason the system held up David's post so I'm forwarding it to the list. (Sorry for the delay, David. From time to time the list does stuff like that and we've never been able to figure out why.) Begin forwarded message:

Joe,
Its freeware like Deep Sky Stacker. You can obtain it here
http://www.astrosurf.com/~buil/us/iris/iris.htm
Its a bit more complicated to use because you're doing all the work. Many more steps than DSS but I really like the results.
Good intro tutorial, and there are some on the download page as well.
