NGC 6741 = PK 33-2.1 = PN G033.8-02.6
19 02 37.0 -00 26 57
V = 11.4;  Size 9"x7"

17.5" (7/16/93): fairly bright, very small, round, clearly non-stellar at 220x, 
fairly high surface brightness, greenish tinge.  Set in a rich field with 
several stars near including a mag 12 star 35" NNW, a mag 14 star 20" W and a 
mag 15 star 30" SE.  A striking equal magnitude double star ?2434 = 8.5/8.5 at 
24" is located 15' S.  At 410x, the easily visible disc is slightly elongated 
~E-W.  The PN forms the SE corner of a rough parallelogram with three brighter 
mag 11-12 stars 2.7' N, 4' WSW and 4' WNW and several other faint stars are 
near.  The planetary has an irregular surface brightness but no clear structure.  
Estimate V = 11.0-11.5.
