This bright 9.4 magnitude planetary nebula extends to a visual diameter of only about 20 arcsec.
However it shows very complex and extended outflows and filamentary halo spanning over several arc minutes quite similar to the northern Cats Eye nebula.
Only few images exist from this nebula, a HST image showing the bright part of the nebula you find here.
