Description:
  25x: The cluster is 45' SE of a star Delta Sct. The cluster is 
moderately bright, 2' in diameter with one 9.15-mag star much brighter 
than the others. Other stars can't be resolved.
  48x: 4 close bright stars shaped like a kite. Although my astro 
software shows fainter stars to be _outside_ this "kite", I saw the 
nebulosity _inside_. Maybe it's just bad seeing.
  79x: The same 4 stars with the same nebulosity inside.
The cluster was 30 deg above the horizon.
