Description

Epic globular cluster with a diameter of 150 light-years and an estimated 10 million stars. I expected the formation and evolution of globular clusters would be well understood by now, but many mysteries still remain to be solved. Great through an eyepiece under dark skies, and relatively easy to image … even for me.

My previous attempts to image this with cooled astro cameras have been hampered by loss of colors during acquisition or processing. Have learned my lesson, and pledged to limit myself to 30 second subs and use of PI MaskedStretch going forward.
