17.5" (6/28/00): this beautiful, highly structured PN is situated just north of 
a wide double star (9.3/10.2 at 18"). At 280x, the annular oval is elongated 
SSW-NNE, ~90"x65".  A bright 30" irregular knot is prominent at the NE end.  The 
SW end of the major axis has a fainter condensation and the rim is clearly 
dimmest near the double star.  The mag 14 central star shines steadily as does a 
slightly fainter mag 14.5 on the NE edge.  Just off the west edge is another 
14th magnitude star.  The darker center is faintly luminous and the surface 
brightness is irregular over the entire oval giving a mottled, wispy appearance.

13": bright planetary with unusual structure and several stars involved.  The 
striking complete annular ring is elongated SW-NE.  A mag 14 central star mag is 
visible as well as a mag 14 star at the NE edge and a faint star is off the W 
edge.  A small brighter knot marks the ENE end.  The planetary is located just N 
of h1606 = 9.3/10.2 at 18" separation.

8": unusual structure, curves south on the west side.  A faint star is embedded.
