Alan,

I'll mail you & Milton a DVD of the movies.

If I can make it, I'd love to attend the Hamilton meeting on Apr 9th!  The only complication is that my son was chosen by his school to compete in the Toronto Regioanl Science Fair which starts that day.  His topic:  Measuring the Speed of Light with a Webcam and a Telescope!

Hi Jim,

I can't make out the individual frames in this file, but the contrast in the lead frame seems very low. I would love to see the video you captured sometime if you have a chance to burn it to disk.

BTW, I will be speaking for the Hamilton club on April 9th... perhaps some from Toronto might be interested in coming down?

best,

Alan

Thanks Milton & Alan,

You know, I tried stacking automatically and hand selecting sharper frames and still really poor results. I don't get it either. So I shrank and downloaded 1 second of footage for you guys to study. The raw stuff looks promising but after stacking I can't really get any great improvement with sharpening tools.
