Just a quick Omega Cen (3hrs, 48mins). Don't think I've had a crack at this one since my first year of astrophotography.
Amusingly I really noticed how bad my tilt was on this target. Inspired me to get off my butt and fix it last night....... after imaging this target. It's actually worse than it looks in the final product here because I did careful, selective deconvolution with different motion blur PSFs to mitigate it. Still it's pretty clearly not right, but much better than it was.
Superb resolution, and perhaps more importantly, you've got the colours bang on. There's a bright B9 class star about half way to 4 o'clock which you show as blue, and a bright K0 class atar most of the way to 5 o'clock which you correctly show as yellow. There are those who would have both of those stars blue, so the whole 10 billion year old cluster is bright blue, a physical impossibility.
And ... you've got North at the top. That really helps people compare. For example, there's that lovely "southern cross" asterism (again with perfect beautiful colour) at the three o'clock edge of the cluster, which is easy to spot in your image.
I am somewhat immune to the grandeur of Omega Cent but this one took my breath away.
Wow, look at how tiny some of those stars are. That's a real trademark of a top notch Newt They seem to get the tiniest stars of any type of scope, even APOs.
Nice to see colour in the Omega C, so many of these images lack the true colour rendition, likely because of blow out.
Thanks Glen I used photometric calibration in PixInsight with a G2V white reference so the colour should be about right.

Great Image
Thanks Col, glad you like it :-)

Thanks very much M&T! I don't even know what those classes are, but I'm glad I got the colour right
10 billion years... makes you realise how trivial our existence is.

I am such a fan of your images.
Greg.
Thanks Greg, that's very kind of you I have to say, I didn't expect such positive feedback, I figured most people are immune these days.

Thanks very much Richard! :-) I tried to strike the right balance between contrast and brightness.

Hi Lee,
It is marvelous what a bit of doctoring can do these days, you would have no problems adding that one to your collection. Most of us start off on Omega Centaurus and M42, then forget about them, years later you revisit them to find that they are still breath taking displays.
Hey mate, I am getting a fatal error when clicking on the link to your astrobin image. Even if I go to your astrobin gallery and click on the thumbnail I get a fatal error.
I am also interested in your comments re white reference, can you let a bit more of the cat out of the bag?

Thanks Peter :-) Yeah, it's easy to forget about those lovely bright ones we started out with. I did the running man again this year too and would have done M42 except that it would require doing a mosaic with my rig.

Looks like Astrobin is having some issues at the moment, I'm getting the fatal error when trying to view large images too... happening with my images and other people's too from the look of it. Hopefully Salvatore has it fixed soon.
Regarding white reference, I was just being a smart arse because when you use PhotometricColorCalibration you choose a white reference (it defaults to "average spiral galaxy") and depending on which white reference you use, you'll get different colour in your image. You can find more details on it here
I have to say, I didn't expect such positive feedback, I figured most people are immune these days.
