17 19 11.7 -18 30 59
V = 7.6;  Size 9.3

17.5" (8/1/92): at 220x, bright, fairly large, 4' diameter.  The bright core is 
elongated N-S somewhat like M4.  The outliers or field stars appear to extend 
the halo E-W.  The halo is fairly well resolved into two dozen mag 13.5-14.5 
stars.  The core is very mottled and lively and just breaks up into numerous 
densely packed mag 14-15 stars.  At 420x, the core is easily well-resolved and 
two very close double stars are at the W and E edges of the halo.  The dark 
nebula B64 is close SW.

8": very mottled, few stars resolved at edges at high power especially on the E 
side.  Dark nebula B64 is close SW.  N6356 lies 75' NE and N6342 75' SSE.
