NGC 7380 and Sh2-142 Nebulae

NGC 7380 is an open cluster discovered by Caroline Herschel in 1787. Open cluster NGC 7380 is nicely intertwined with a bright diffuse nebula which bears the catalog designation Sh2-142.
Caroline Herschel discovered this cluster in 1787, when her brother William was absent. As usual, William Herschel included his sister's discovery in his catalog, and labeled it H VIII.77.

This color composite image is based on data coming from several photographic plates taken between 1989 and 1991 through the Palomar Observatory's 48-inch (1,2-meter) Samuel Oschin Telescope as a part of the second National Geographic Palomar Observatory Sky Survey (POSS II). The photographs were recorded on two type of glass photographic plates - one sensitive to red light and the other to blue - that later were digitized.
