Is processing Tb of data with a hex-core i-7 PC on the cutting edge... or the lunatic fringe?
P.S.
The 72,000 odd frames needed to make this time lapse were flat-fielded, yet still show: - dust motes
- interference banding
I'm not sure how to fix either.

hang on a minute - how many grabbed frames make up a final frame to go into the mix? with your capture software are you flat framing with every capture? I have found that for a long duration data mining grab the sky changes heaps and what was the initial frame is very different to the final frame in brightness and details. that's why I made sure that the sensor was a pristine with no visible moates anywhere as the flats didn't work. but then that could be me and lack of skill? lets hope that today's clear skies allows you to get the edge on with lots of loops and maybe an eruption. I caught a CME on the edge some time back and the 5 hours of time I took the whole capture the cme event was over in less than 15min. I was lucky I was taking captures every minute - roughly 600 odd frames with only the best 100 of the m used. not much to show for it in the end as I had only 300 final processed shots at a 10 frames per second rate making it a very boring 30 second clip.
