Looking for something to image early in the evenings last month while I waited for my preferred targets to rise, I shot a few images of Omega Centauri.
Here is the result - 4 hours Lum and just under 1 hour each of R, G and B in 5 minute subs.
Taken from my dark sky site near Coona at the iTelescope facility with a PW CDK12.5 and STX16803.
Processed (roughly) in PI.
Here is a link to a larger version.

Nice one Pete! Very bright. Gotta love secondary targets, some of mine come out better than the primary object :rolleyes::D

That's a terrific Omega. How long were the subs? Nicely processed. One suggestion - the framing is potentially good as you framed it to catch that pretty blue star to the right. But if you rotated the image a tad and cropped the image a small amount to go back to square shaped that blue star would be on the diagonal of the image and would present the whole scene more aesthetically.

Nice one, Pete! It's a nice bright target and doesn't need a lot of fancy processing.

You are not wrong there Rod.
I haven't imaged OC for years - it was a good decision
Thanks
Cheers Rick. I find processing globs tough - do you darken them so as to accentuate the colours or leave them bright to highlight how many stars there - and there are so many!
Thanks Justin

Thanks Greg
5 minuts subs - binned x2 for RGB and unbinned for Lum. I find it hard to justify shifting from that setup as it works well for this rig. I have it pre-programmed in CCD Navigator so its the default setting for all my images.
Can't work out how to rotate in PI (other than by 90 degrees) - though I am sure there is a way. So I cropped and rolled it that way - its not centred and I have cropped more than I would like but I do see how the visual appeal is improved by the framing. I haven't given much thought to that in the past - I'm more interested in finding a guide star - but I see why you are keen on it.
