With all that data wonder what would happen if you aggressively culled frames with subframeselector, and tried to the tightest "lucky" frames. With so much data your almost able to use planetary-style techniques that only normally make sense with fast frame video data perhaps?

(and stop having so much fun!! )
Thanks Rob. I will give that a try at some point. For now I'm relying on the weighted batch processing script to assign the weights well (looks like it is using FWHM, eccentricity, star count and SNR in the weighting). I haven't dug into what weights it assigns to each yet.

I have experimented with subframe selector however I haven't figured out an efficient way to use it so far - I end up searching for certain subs to remove them from the stack manually.

Thanks Dave. Good to have some data to process even if it is from light polluted Brisbane.
