Here's an object from a couple of nights ago when I was imaging the Milky Way. This one had my head scratching for a few moments as I was trying to remember which part of the sky it was. I knew the general direction so it didn't take long for me to confirm a few stars around the cluster. It's been described as an open cluster with a series of visual double stars. Another signature feature is the series of three stars just above the cluster.
They're just a little under and little over 2 arc minutes apart. It's quite pretty and hard to miss in even a small refractor.
