Interesting looking shock fronts and with delicate tendrils of OIII. That's what a 20" gives.

Nice detail.

Thanks, Paul. The challenge for us seems not so much capturing the faint OIII nebulosity as seeing it between the blinding stars. Easier at altitude or in the desert perhaps. Had a look for Steve Crouch's image. Found one on RCW 57 or so.

Nice work on imaging things that are rarely imaged.

Greg.

Thanks, Greg. There's not so much about it. I thought, where did I get the "magnitude 18" from? Did I just make it up? Eventually found it in Imaging the Southern Sky by Chadwick and Cooper.

Thanks, Fred!

Although Don managed to capture more detail, his interpretation is way too red for me; I like how you balanced the colours. I think this target might be a good candidate for an ongoing project- maybe you could add more data one day/night and see if that helps to bring up the faintest bits even more?

Having said that, I think it is a fabulous image of a very difficult target - I do not even think of imaging objects past magnitude 10

Thanks for the encouragement Slawomir. You are right that perhaps four times the exposure would be worth the effort, to get the grit out of the [OIII].

Thanks Rick. We almost wonder with this one if it would be better to show it as two quite separate shots, one monochrome in H-alpha, and another in OIII, because it's so faint and hard to see against the glare.

I love the road less well traveled. What a faint challenging object -!!

I hope to see more data on RCW 104 . You are correct, there seems to be nothing else of any value [apart from Don Goldman's] done on this.

Excellent!

Tim

Thanks muchly Tim, we're delighted. We'll definitely try adding more data.

Cheers, Rex, glad you like it. Really does look like a cosmic giant clam.
