Notes: This field was tough to process ... there is extensive faint background nebulosity (galactic cirrus) in this region, as shown by the image by Stefan Binnewies and Josef Popsel on this wonderful Planetary Nebulae page from the Capella Observatory. My conditions and filtration are not optimized for recording this kind of chaotic background. This is one faint planetary to have an NGC designation (as opposed to only PK).

18" (10/9/04): picked up at 73x using the OIII filter as a fairly faint, round, 
evenly lit 90" disc.  Good contrast gain with the filter.  Faintly visible 
unfiltered at 160x as a moderately large but low surface brightness halo 
surrounding the 13.5 magnitude central star.  A faint mag 14.5 star is atf the 
NE edge of the halo.  A string of 3 mag 14-15 stars is ~2' NE.  Images show the 
a complex multi-rim structure (brighter along the west side) with a darker 
center, but visually the planetary appeared pretty featureless.  Located 7' S of 
a mag 10 star (SAO 107277).

17.5" (10/2/99): at 100x and OIII filter appears fairly faint, round, moderately 
large, 1.5' diameter, even glow.  At 220x without filter, the central star is 
easily visible surrounded by a round, low surface brightness glow.  A very faint 
star is at the NE edge. No annularity seen.

13" (6/18/85): at 62x with filter appears faint, moderately large, round.  
Without a filter the faint mag 13.7 central star is visible surrounded by a very 
low even surface brightness halo 1.5' in diameter.
