18" (8/17/04): at 160x, ~40 stars are visible in a 8'x6' group, extended SW-NE.  
The cluster is dominated by two mag 7 and 8 stars that are separated by 1'.  
Both of these stars have much fainter companions.  Another nice, mag 13 pair is 
SW of the mag 7 star.  Stands out well in the field.

17.5" (10/5/91): about three dozen stars in a 7' diameter.  Very bright, 
elongated SW-NE although scattered outliers make the cluster rounder.  Includes 
several fairly bright stars with two stars mag 7.0/7.9 at 1.0' separation NE of 
center which are surrounded by a semicircle of nine stars.  Includes several 
double stars with a mag 10 star which has a very faint companion on its W side.  
Not rich but distinctive.  Mag 6.8 SAO 19698 is 11' NW at the edge of the field.

8" (10/31/81): about two dozen stars in a bright cluster, not dense, includes 
two mag 8 stars.
