V = 10.6;  Size 5.8x2.2;  SB = 13.2;  PA = 43d

17.5": bright, fairly large, elongated 5:2 SW-NE, 5.0'x2.0', mottled patchy 
appearance, small elongated brighter core but no nucleus.  A mag 15 star is 2' 
off the NW side.  Faint spiral structure visible with concentration.  An 
extremely faint arm is off the NE end curving towards a mag 14.5 star to the NE 
3.7' from center and a second extremely faint arm is just visible off the SW end 
curving to the south.  Forms a pair with N4085 11' SSW.
