Many thanks, guys!
Marco, I'll make a mosaic next year.
Rob, yep, this was a rough process straight out of PixInsight; I will be mindful of all the channels as I process it thoroughly.
Sadly, I won't be attending Astrofest. Too much on with work. I don't have any leave (bring on long service leave in April!) and never even thought about asking for a domestic visa.
One day...
