20 41 05 +16 37.3

17.5": very scattered group of mag 9.5-13 stars in roughly a 10'-15' region.  
Barely stands out in the 20mm Nagler field and not worth noting as a cluster.  
There are no specific borders but the stars have the appearance of being aligned 
in strings or groups.  Most prominent is an elongated group oriented WNW-ESE 
through the two brightest mag 9-10 stars (brightest star at 20 41 10.5 +16 
38.9). A small line of three mag 13 stars are near the western end of the 
string.  Appears to be a random grouping and listed as nonexistent in RNGC.

Historical Research Notes / Correction for NGC 6950
NGC 6950 looks like a good, if scattered, cluster on the POSS1 prints.  It was
seen by both WH and JH, and their positions and descriptions agree.  Still, no
one has included it in a cluster catalogue, and RNGC has it as not found.  I
suspect, though, that it could be easily dug out with a six- or eight-inch
telescope. - Dr. Harold G. Corwin, Jr.
