Description

While at Eastman Lake, our local astronomy club's main observing area, I decided that I was going to try to attempt to image Omega Centauri. Eastman Lake, located in the foothills of Madera County in California, is at latitude of 37 degrees, 13 minutes, and 9.5 seconds. At this latitude, Omega Centauri creeps just 5.7 degrees above the horizon and, due to the hills and trees, is visible for a mere 17 minutes.

This story is told well in this image, where the beautiful Omega Centauri is seen dancing just above the tree line, blurred from the motion of the telescope and the stacking process.
