NGC 6826 The Blinking Planetary
Magnitude: 8.8
Distance Aprox: 2,000 light-years
Diameter: 130 light-years
Constellation: Cygnus
It's a compact object that blinks on and off when observed, hence the name Blinking Planetary. Most planetary nebulae exhibit this type of behaviour but with NGC 6826 it's particularly obvious. When you look directly at the central star the nebula tends to fade away but glancing towards the edges - using averted vision - it suddenly re-appears. Switching back and forth rapidly between averted and direct vision causes the nebula to dramatically blink on and off.
