The nebula has a figure elongated in north south direction, has a width of 7arc minutes and about 27 arc minutes or so in length. Sh2-204 is floating about 13 thousand light years away, emitting reddish light activated by bluish stars with 6th or 7th magnitude in brightness surrounding the nebula. These stars are forming a sparse group called the Cam OB3 association.
