This is a fairly large sized planetary nebula in center of Lynx.
The nebula has a visual diameter of a bit larger than 6 arc minutes, we can capture it with telephoto lenses.
But it's very dimmed so we can hardly appreciate through telescopes.
This nebula has an anomalous figure with a round rim with a rectangular hole.
