Oh no not another NGC 6744

LRGB IMAGE 4.5 hrs L, 1 hr R,1 hr G, 1 hr B, ST-10XME, BRC-250

Played around with Pixelinsight on the NGC 6744 data to see if it worth purchasing.

It is a poor image as the colour doesn't look right.

Higher resolution here.

Looks great to me!
Starry Night reports it Mag 15, Wikipedia Mag 9 ?? I'll give this one a go, but if its Mag 15 at that size, I might pass!

Good detail, Steven. A bit of tweaking on the colour and it would look great.

NGC 6744 tweaked

Thanks for the feedback.

NGC 6744 tweaked by removing some cyan.

It's a companion galaxy, NGC 6744A.

Looks great, Steven-lots of nice detail there, and colours definitely better in the second one

Nice work Steven. This sure is a difficult galaxy and you have the faint bits. Colour balancing on this dim stuff sure is problematic - if you work out a foolproof method, please post it... regards Ray

Ive found this one difficult too. Given the amount of data on such a dim galaxy thats pretty deep, and the colour balance is OK, I just couldnt get "brown" highlights in the core at all.

Fred, Ray

I think this is one of those objects that requires significantly longer colour exposures.
My rule of thumb of using 1 hr for each of the colour channels works for most objects...... NGC 6744 isn't one of them.
