Do not wish to be a bother but can you point us to a reference document that will tell us how to go about what you suggested. We can spend several days trying to wade through AstroImage J documents to figure this out. We are not professionals or do not have a let of computer programming skills so any help would be appreciated. Also in the middle of a build on a knew imaging system so a little stressed and and stretched right now trying to work through the technical issues.
If we can figure this out would like to show this to others in the amateur astronomy and satellite observing community because believe it could lead to a better way to estimate tumble rates off of video. Right now the majority are still using just stop watches to make these kind of estimations.
Karen your estimation is close to what we get and seems to agree with the Riddle student. The issue is also sub picks which are important to since we are dealing with a satellite tumbling on multi-axis
Thanks once again for the help and it is greatly appreciated.
Regards
Thomas

Hi Thomas,
I have no expertise in this area, but I watched the video and I see a ~2
sec period in the main brightness variation. If that is caused by
tumbling (I don't have the experience with satellite imaging to know),
then why can you just run straight forward aperture photometry on the
time series and measure the period precisely?
