This is 13x10min in Ha at prime focus on my 5" newt. Might be a candidate for a mosaic as there's a lot more of other interesting stuff in the area. I'll definitely try to do a colour version. Skies were pretty pathetic tonight in Western Sydney. Lots of smoke - when it's not sausage sizzles it's back burning - but again Ha saved the day. I'll have to add more data tomorrow night.

Thanks for looking.
