Messier 22 Globular Cluster

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 :).
