Omega Centauri from Central Florida, Spring, 2012

This is the most glorious of the globular clusters! It only reaches to not quite 13 degrees above the horizon from the location this was taken, so it is imaged through about 4.4 airmass values . . . hardly ideal.

On a personal note, being a denizen of the northern hemisphere, I never expected to even see, let alone image, this magnificent southern object. I am very pleased at how well the image turned out considering the cluster's very low altitude and the very short time I had to work with it.
