Well, I was trundling along quite nicely shooting some Ha in the B33 region, when after 30 mins the cloud rolled back in.
Anyway - here's the perennial fave after 30 mins-worth.
QHY-9, Sky-90 and 7nm Baader Ha, MaximDL to capture and stack 6x 5 min subs.
Yes, I'm waiting for the flattener - and will be for a while... (darn it).
No where near Marc's effort from last night though...

So far in so little time, your on a roll, bodes well. 6 min subs for Ha is a bit short though, patience grasshopper ;-).
Cloud?, its clear as here now...?.

Thanks very much David! :) It's early days, but I reckon that it's going to be a ripper! :)
Thanks Fred. It's all good fun and experience :) BTW - a typo. I meant 6x 5 min subs. I've corrected.
I've set up guiding fairly well tonight, and I was going to go for at least 10-min subs to see what happens... but the cloud sorta rolled in. I'll give it a little while and see what happens. I'm half way to Canberra you know... not on the North Shore... :P You guys have weather gods up there who listen! ;)

Chris, Ha needs long exposure to get the best results (except if you are using a F1.8 hyper thingy, then 2 sec is over exposed :P). Get a half dozen 20 min subs and stack them, makes a huge difference. Not too shabby for 6 min jobs, you have a lot to look forward to no doubt.

20min subs all the way in Ha Chris!! :) Good going in any case but with the KAF8300, as any sensor below 80% QE, exposure is king!! You, just like myself, have been spoiled by high QE cameras in the past, where 5min Ha subs are enough! :)

That's a top shot for such little exposure time. Certainly delivering the goods. :thumbsup: Don't be shy in pushing the data in your processing as there is far more in this shot than meet the eye.

Thanks Mark, Alex and Marc :)
Yep - more processing to do Marc. I managed a few minutes-worth before climbing into bed last night. Will see what happens with it today. It was disappearing into the western horizon when I finished with it. :) I was just getting to the 1200 sec exposures when both the sky and my eyelids went. LOL!
I've left the mount set up outside overnight, so I hope that it's OK for tonight to get more time on it - doesn't look promising though. :(
