I share with you my version of the Sh2-142 nebula, called Mago for its shape. This is an emission nebula located about 8,000 light-years away in the constellation Cepheus. Inside this object, about 100 light-years wide, the stars that form the open cluster NGC 7380 developed. These celestial bodies, with their emissions, then modeled the cloud of gas and dust making it assume the 'current appearance.
