This was one of those cases where I was tempted to chuck the data. I had foolishly fiddled with the collimation during the session and the sseing was bad, so I had egg-shaped blobs instead of stars. Then along came Russel Croman's BlurXterminator--an AI based deconvolution process--and I ended up with something reasonable. Just goes to show: don't chuck away data.
