Wild Duck Cluster and M26
The Wild Duck Cluster (M11) is an open cluster like Pleiades only ten times further at 5,500 light-years. The cluster located in the constellation Scutum contains a few thousand stars as opposed to globular clusters which contain tens to hundreds of thousands of stars and are much older. The name comes from a 19th century English Naval Officer, Admiral Smyth, who thought the cluster resembled a flock of wild ducks. (source:

M26 is also an open cluster in the constellation Scutum is approximately 22 light-years across and 5,000 light-years distant. The cluster contains 229 stars making much smaller than its neighbor, M11. (Source:, Wikipiedia)

These clusters represent 35 and 36 on my Messier Objects with an ED80 list, not that anybody is keeping track.
