17.5": bright, fairly rich group surrounding two mag 7.5 and 8 stars (SAO 77842 
and 77839) oriented N-S.  There are about three dozen stars mag 10-14 in an 5' 
well-detached circular group with several double stars including a faint pair 
preceding the northern mag 8 star.  The southern mag 8 star has a couple of very 
faint companions.
