(IAAC) more blinking planetaries


Here are some more results from searching for the sting
"blinking" in my observations.

From Sagittarius:
NGC 6629  Pretty bright, small and a little elongated at 220X. It is
greenish and will reveal a central star with direct vision at 220X.
It exhibits some of the "blinking effect"--the central star is much
more prominent with averted vision than looking directly at it, so it
will blink on and off as you look at the nebula then look away.  This
small planetary is about three times the size of the Airy disk on a
night I rated 7/10 for seeing.

From Canis Major:
IC  2165  pretty Bright, Small, Round, found at 165X.  Greenish,
brighter central section, dimmer outer shell at 320X.  Slight blinking

So few objects show the "blinking effect", they are certainly worth
