Located
            in a star rich field in Cepheus, this bright gem is also known
            as Sharpless 2-158. Spanning 10 x 6 arc minutes in size, this
            is part of the larger bubble nebula complex and consists of two
            11th magnitude hot stars surrounded by a structured assemblage
            of bright looping hydrogen nebulosity.
