Hi all,
I really
did go loopy imaging this object! It took me 4 nights of imaging to gather a mere 7 hours data – one of which I threw away when processing. Clouds, moon and power failures conspired to make what should have been maybe a 2 nighter (yeah – I’m slow) into long drawn out affair over close to 2 weeks.
Anyway, this was my first attempt at using a Ha filter - an interesting processing challenge! It’s really a bunch of NGC objects -3576, 3579, 3581, 3582, 3584 and 3586 . 3576 is actually the little fuzzy off to the bottom right of the centre bright region. The complex is commonly referred to just as NGC 3576 though.

Image details -- L(R+G+B)HaRGB – 60(60), 120, 60, 60, 60 minutes total with 15, 30, 20 minute subs (L, Ha, RGB respectively).
Comments and critique welcome. I'm sure I haven't finished tinkering with it yet!
