Thanks Rusty.

I can't do any of the targets you have suggested Aidan. I haven't had a usable night in over six weeks. All of the single frames I have posted are from old stacked image sets. Your first suggestion, O. Cent, was one of the first
objects I posted in this series, and is probably my favourite of the series; and M16 followed shortly after, if I remember correctly. I'm currently looking at my frames of 104 and 47.

P.S. Can't find M16, but O. Cent is sixth item down 3 pages back,[astrobin item]. Best viewed at 75% screen.
