V = 7.1;  Size 480"x340"

18" (8/23/03): breathtaking view at 215x; with the fainter but larger outer 
lobes increasing the dimensions to nearly 7.5'x6' and the ends of the major axis 
seem to open up and bulge out.  With careful viewing, ~10 superimposed stars can 
be counted including the easy mag 13.8 central star.

17.5" (6/15/91): very bright, very large, 7'x6', bright dumbbell lobes are 
oriented SSW-NNE.  The SSW lobe is brighter with a bright outer rim.  Large 
fainter sweeping side lobes fill in the dumbbell and reverse the major axis to 
WNW-ESE. The planetary has an irregular surface brightness with a darker center.  
At high power 5 or 6 stars are superimposed including the easy mag 13.8 central 
star.  Overall, this is the most impressive planetary.

8": central star visible at 200x, fainter side lobes prominent.
