Messier 22 Globular Cluster

[TR]

This is one of the brightest globulars visible in the night sky and near the Galactic bulge region in the constellation Sagittarius. It has a few names, M22, Messier 22, and NGC 6656.

It has an apparent magnitude of 5.5, making it an interesting object visually. Through a modest instrument, hundreds of stars can be resolved. M22 is one of only four globulars of our galaxy known to contain a planetary nebula.

I tried something a little different with this object. I captured only Red, Green, and Blue filtered light. I aimed to reveal as much colour as possible in the core. Hopefully, it’s not too over the top :).

Red 24X600 Binned 1X1

Wonderful image Terry! Beautiful star colours and tight and well defined all the way into the core. It just beckons you to keep zooming in and never disappoints! Lovely

Lovely image Terry and I love this glob, during my first nights up at Eagleview, back in mid 2021, it was so easy to pick out naked eye, looked like Omega does from a suburban sky, I knew then it was a dark site :)

Thanks Dave

Could you imagine living there, surrounded by so many stars. I don't think I could sleep. :P with all that light.
