I'll check again tonight when I have access to that laptop.
I was looking in C:\Users\SJAA\Pictures\SGP\M51\Bias and only found the
number of files corresponding to one run of the sequence, instead of 5.
I did move them to C:\Users\SJAA\Pictures\SGP\Bias before "organizing" so
maybe I didn't get them all checked in the move process (would have done
control A, however).
Thanks for checking the logs and I will report back.
