From the NGC / IC Project:

Contemporary Visual Observation(s) for NGC 6705

NGC 6705 = M11 = Wild Duck cluster = Cr 391
18 51 05 -06 16.2
V = 5.8;  Size 14

13.1": at 140x, several hundred stars mag 11-15 and a brighter mag 8 star (SAO 
142695) in a 10' region form a remarkably rich cluster including some dense 
knots of stars.  A starless vacuity is visible just W of center at medium power.  
Dark lanes appear to wind through the cluster at high power grouping the stars 
into chains.  Several dark nebula are near including B108, B112, B318.

8": this is the most impressive open cluster with this aperture.  Appears as an 
extremely rich carpet of faint stars and dense clumps in an arrowhead shape.
