to me, it looks better than the first example. although, very noisy.
you could take flats now and add them to DSS file list.
the camera orientation looks easy enough to replicate - which is the important thing in flats.
(google how to take flats)
(you might need to work with "
file groups" because the date stamp is different. but I'm not too sure about this. give it a try in the Main file list tab and see whether the flats are listed in the To-Do-summary of the stack.)
