BEAUTY: 
BRAGGING RIGHTS: A beautiful sight
HOW EASY IS IT TO SEE? Best with a high-power telescope
BEST TIME TO SEE IT: Summer (in Cygnus)
TYPE: Planetary Nebula DISCOVERED: 1793 by William Herschel
Averted vision. The Blinking Planetary consists of two concentric shells: a bright inner shell and a larger, but dimmer, outer shell. When you look at it with direct vision, the bright inner shell is visible, but the outer shell is too faint to see. When you look away, the nebula seems to grow in size. Try it!
Find this enigma next to 16 Cygni, which is itself about 6 degrees north of Delta Cygni (see chart). The Blinking Planetary is tiny, and at less than 50× you may not see much more than a star. Try 100× to see more of the outer shell. If your skies and telescope allow, keep increasing the magnification and see if you can detect any detail.
