Chuck, I have not noticed that effect. I have seen the blinking phenom in 8-22 inch scopes. I have noticed that once I knew why it blinked, it didn't blink as much. David, I use the Limicon oIII and the Lumicon UHC the most, but I also enjoy the Del Woods filter I got a long time ago. Brent --- Chuck Hards <chuckhards@yahoo.com> wrote:

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.
