Hi Ron;

I imaged it back on March 27, 2004 using my EQ2/3 mount and a MAK 127 mm scope at 1540 mm focal length.

Notes on the above are down near the bottom of my web site:

I was shooting a movie clip every 60 seconds, then stacking each one. I believe this was at 7.5 fps and capturer around 230 frames per movie. Astro IIDC didn't have stacking back then, so I used Keith's stacker.

There were AppleScripts I included in the final DMG that can automate this process quite easily now. And once you have the stacked images, Astro IIDC can convert them back into a time lapse type movie pretty easily using "Images to Auto Aligned movies…" and then compress the resulting ARGB32 movie into an Mp4 using "Export Movie…" for a web site.

HTH..

Hi,  if anyone is paying attention to this list, I'm wondering what others might recommend for imaging the Jupiter moon triple transit w/AstroIIDC friday-Sat. nights?   Is the best way to create a time-lapse from say a series of 30 sec. movie stack and create a series of still frames?  What time interval would you suggest?

thanks.   Ron
