Had a lot of fun with the Blinking Planetary last night after viewing some doubles nearby
in Cygnus! The blinking effect was VERY neat and very apparent.

Look straight at this planetary and you see a magnitude 11 or so star, stark against a
black sky background.  Look away just a fraction of a millimeter, and you see a VERY
bright hazy round nebula surrounding and almost obliterating the star. You can very
slightly alter your vision to off center to keep seeing the planetary coming in and out of
view.  In our 12.5 inch it was a very bright almost solid patch of nebulosity.  Really
