This target was NOT on my planned list to do, but this was on a night when the Mount would not GOTO anything, and after creeping across the sky star hopping I managed to find Sadr and some nebulosity, so rather than waste any more of the clear night, decided to stop there and image what I could and I had no idea which bit of the Butterfly I was going to acquire.
I therefore had the most unsuitable of cameras on the scope which was planned for a different target. so I only have a small section of this nebula. Not particularly attractive on its own.

do you do flats for your OIII and SII?
Yes I do them for all the filters. Olly says no need if you have an enclosed filterwheel, but I always take them just in case.

you need to take flats for all of your filters,
you never know what junk is on your filter itself,
