With the publishing of my image of M22, I have now captured the brightest four globular clusters in the night sky; Omega Centauri (https://astrob.in/1tevp9/0/), 47 Tucanae (https://astrob.in/309427/0/), Messier 22 (https://astrob.in/i3mo35/B/) and NGC6752 (https://astrob.in/qd3t6r/0/).
I figured that they would make for a nice composite image and so have done just that.

I do find globular clusters to be fascinating objects given the age of their stars and the 'wow' factor when showing people the objects through the eyepiece.
Thank you for dropping in for a look and I hope you enjoy the journey :)
Clear skies,
Rodney

Nice set of globular clusters Rod. They are my favorite object to image and view as well. Thanks,
John W.

All superb Rodney.
Question: Omega Centauri and Crackerjack are in the Milky Way, hence lots of field stars. 47 Tucanae is far from the Milky way, hence few field stars. So far so good. But the Pavo globular is also far from the Milky Way, yet there seem to be lots of field stars. Is that because the Pavo globular is fainter than say 47 Tucanae, and "exposing" to see the globular at its best brings out more field stars?
Best,
Mike

Thanks John/Mike, yes we do win - every time we go outside on a dark clear night and look up at the southern skies :)

Thanks Mike. We are talking about a brightness range from 3.9 for Omega Centauri to 5.4 for the Pavo Cluster. For the Pavo Cluster I would have stretched the image to bring out the detail in the core of the cluster and the rest of the star field would have come along for the ride. This being the case it would make sense that the background star field is maybe a little more prominent.
