NGC2346 is a planetary nebula in central Monoceros, about 40 arc minutes southwest from δ Monocerotis. We can appreciate only central region of nebula through larger scopes. Actually the nebula has very dimmed structure like tubes stretched north and south direction, this image shows you the structures barely. The Hubble Space Telescope (HST) has captured a clear image of the nebula.
