Also known as Caldwell 15, the Blinking Planetary measures 27 arc seconds by 24. In a low-medium power view such as on the left, the striking and beautiful turquoise colour of the small disk stands out distinctly against the background. At higher power as shown above right, more structure within the disk is obvious; an inclined ring-like structure surrounding the bright central region, all within a circular halo. The tips of the rings poke through the halo on either side. NGC 6826 is about 0.2 light years across and 2000 light years away.
