the Blinking Planetary, NGC6826,
Brent, have you noticed that the "blinking" effect seems to lessen with increased aperture?
From my experience, the effect is most pronounced with 6-to-12 inches of aperture. Above that, the effect begins to dimminish.
I'd like to add that, with proper filters, planetaries in general are excellent targets for observers in light-polluted locations. The year our daughter was born found me at home virtually every night, yet that summer I managed to detect over 100 planetary nebula from my West Valley home, using a 10-inch Newt and LPR filters.
