Observation Notes:<\/b><\/p>\n

This misty cluster shared the same low power field of view as NGC 663 to the south. At 120X, the cluster takes on a triangular shape with several doubles throughout. A bright star marks its southern apex. Of the 58 stars plotted in the sketch, 28 were within what I perceived to be the boundaries of the cluster. A couple of the brighter stars are likely foreground objects. I made the mistake of leaving the eyepiece at an uncomfortable angle, right over one of the tripod legs when I began what turned out to be a 40 minute long sketch. I wasn’t able to slide the chair up to it, so I ended up tip-toeing my way through the last half of the sketch. That was a bit of a bummer.<\/p>\n
