This one is a work in progress and hopefully I'll get colour when the moon goes away. Probably should make a good HaRGB image.

Very nice Steve Good framing, you got all the features in and its all very clear and highly detailed.

Wow! Very nice - not often imaged that wide. Bring on the colour!

Thanks again Marcus. Yep - I wish that moon would go away.

Steve, I enjoyed seeing how the nebula gradually fades into the field and merges with a rich star cloud. This is only obvious to the visual observer on absolutely perfect nights.
According to the Sky Catalog 2000.0 volume 2, and some of the other versions of the NGC catalog that I have seen, NGC 6188 is actually only the 15-20 arcmin core of a much larger nebula;
the giant 2-degree-scale HII region that is known as RCW 108.
Amateurs persist in referring to the entire giant HII region called RCW 108 (which reminds the observer of a ghostly version of the Eta Carinae Nebula) as being NGC 6188, but I think they are wrong to call the entire nebula NGC 6188.
I will take up this issue with "NGC/IC Project" people, who are the world authorities on these arcane and difficult matters of correct vs incorrect object identifications.
I shall report back the answer I get from the "NGC/IC boys" such as steve gottlieb and wolfgang steinicke!!

Yes I think you are correct Robert

Excellent detail Steve.

I see them there Fighting Dragons ;)
Awesome field Steve :thumbsup:

Ah yes - forgot about the fighting dragons. Thanks Mike. Be interesting to see how the dragons look in RGB.

"Fighting Dragons" is a good and memorable name.
Has it caught on?
I usually call the entire 2-degree-scale HII region "The Ghost of Eta Carinae", simply on account of its large angular size but its low surface brightness.

:lol: don't think so but yes I recon it's a good name none the less :thumbsup:
Getting people to see the running chicken is hard but most people see the fighting dragons straight away :)

I think that giving objects in the southern sky common or familiar or poetic names helps to familiarize it. I seem to recall that Peter Marples was collecting some of these "We call NGC ____ the swiss cheese in the sky" types of names.
It would be so much easier if some of the dreaded two part ESO galaxy identifications e.g. ESO123-025 , and those very long PGC galaxy identifications, had more easily remembered names!!
The northern sky has had many more years of myth and lore and emotional familiarity with the human race, than has the southern sky....and this is probably why there are so many "homely and familiar" names that have eventually stuck to become the real names of objects.
Unfortunately, I personally never see dragons or birds or heros or any other creatures in the sky......I just haven't got that kind of imagination, and I only see geometric shapes!!!

Sublime H-alpha image. Yep.
Nice one Steve :thumbsup::thumbsup:

Thanks Peter. I'm staying out of the dragons argument.

:lol: No harm intended... it's just all space Rorschach to me.
