"This is the Corona Australis Molecular Cloud, a dark molecular cloud with many embedded reflection nebulae, including NGC 6729, NGC 6726–7, and IC 4812. A star-forming region of around 7000 M☉, it contains Herbig–Haro objects (protostars) and some very young stars. About 430 light years (130 parsecs) away, it is one of the closest star-forming regions to the Solar System. The related NGC 6726 and 6727, along with unrelated NGC 6729, were first recorded by Johann Friedrich Julius Schmidt in 1865. The Coronet cluster, about 554 light years (170 parsecs) away at the edge of the Gould Belt, is also used in studying star and protoplanetary disk formation."

Nice Kevin that's a great image ! I've been working on the same thing over the past week - maybe a few less subs and I'm still not happy with it. Even less so since seeing yours.
More subs than you can poke a stick at
Nice shot Kevin.
Thanks Colin! I'd take more but I need to move on to other stuff.

A heroic effort stacking all those subs.
Thanks M&T. Stacking is easy. The PC does it in my sleep.

That must be some sort of record for the number of subs!
Greg.
Thanks Greg! I think the Serpens star cloud was more subs so this is not the record. Close though.

Yours looks fine Chris. I had some trouble processing this one too.

Thanks Glen! 30 sec subs have a natural dither effect too lol.
Thanks Bill. Was just looking up Herbig-Haro objects and watching some movies from HST of the polar jets. Protostars are fascinating objects. I didn't realise HST had movies of them! Very cool.
