17.5": at 100x appears as a fairly bright nebulous field locally brightest 
around two pairs of fairly bright stars.  Two mag 11 stars are at the N end with 
a separation of 51" and a pair of mag 9 (SAO 49589) and mag 11 stars are at the 
south end with separation 42".  Connected by a fainter elongated piece of 
nebulosity.  Very faint nebulosity extends NE towards a mag 7 star (SAO 49603) 
located 11' NE.  The catalogued position is centered on the northern pair of 
stars.

8": fairly large nebulous field locally brighter surrounding a wide faint double 
star and to the S surrounding a double star mag 9.  The brightest section is 
elongated N-S.

Historical Research Notes / Correction for NGC 6914
NGC 6914 is the northern-most of three similar nebulae, probably all 
reflection nebulae -- the show up best on the POSS1 blue plate.  
Interestingly, the area on the red plate is dominated by a large HII region,
centered 20-30 arcmin to the northeast of N6914.  Are the reflection nebulae
part of the same system of gas and dust, or are they merely superposed along
the line of sight?  I suspect the former, but of course can't say for sure.
