| Description | I've been despairing how to capture a set of Messier targets low in the southern sky. M55 is one of these, never really rising above my treeline. I sympathize with Charles Messier who had received correspondence about this object, but tried for 4 years to actually view it because it was so low! Paris is at a higher latitude than the Catskills, so it's impressive he managed it at all. I had decided to travel to the Ashokan Reservoir, which has a very low southern horizon... taking a chance that it wouldn't get wiped out by light pollution close to the horizon. |
