Description

The Mushroom Nebula is a grouping of 3 nebulas that are about 8000 light-years distant.  Although they are about the same distance away they do not appear to be associated.  The larger but fainter nebula forming the mushroom cap is SH2-254.  The smaller and brighter nebula in the center forming the top of the stem is SH2-257.  The nebula forming the bottom of the stem is known as IC 2162 or SH2-255.  There are two other nebula in the image.  To the right of SH2-257 is the small SH2-256.  Towards the bottom of the image is the small and faint reflection nebula SH2-258.
