Description

Here's another quickish grab of a low altitude (~15deg) southern target for my Messier collection. It is one of the more distant globular clusters in the Milky Way galaxy, situated some 68,000 light years away and on the other side of the galactic center. The cluster is very densly packed, which at it's distance from Earth makes it difficult to resolve the core into separate stars. I was very surprised to see so many red stars, which I'm wondering whether it's the consequence of viewing them through the concentration of dust along the galactic plane, where blue light is lost through an effect known as Rayleigh scattering.

It's distance from Earth and low altitude certainly makes this a challenging target from my 52N location.
