17.5": about 50 stars mag 10-15 at 220x in a 6'x4' region.  Fairly compact and 
rich with an irregular outline.  Includes a thin isosceles triangle of three mag 
10 stars with the base to the S.  The SE star in this base is a close unequal 
double.  A number of the stars are arranged in strings including four mag 13-14 
stars over haze trail from base to the N.  Also four mag 8/9 stars precede the 
cluster to the NW in a 10' string.
