V = 10.2;  Size 5.2x3.9;  SB = 13.3;  PA = 135d

17.5": fairly bright, large, ~4.0'x2.5' NW-SE.  Nearly extends to a mag 11 star 
2.2' W.  Very bright, very small core increasing to a bright stellar nucleus.  
The galaxy shows signs of spiral structure and there appears to be a short outer 
spiral arm attached at the SE end hooking N separated by a slightly darker 
region between the main body (verified on photo).

NGC position is accurate. The RA in the RNGC is 1.0 tmin too far W.
