Description:
At 135x (15mm Panoptic, 30' tfov), King 10 is an extremely faint group of 8 to
10 stars scattered evenly over a 3'x2' NNW/SSE area.  Averted vision was
required for about half the group.  At 50x (40mm Optiluxe, 1.2d tfov), the
cluster was just detectable as a small misty patch with three stars resolved -
once I knew what to look for.
