The Bubble Nebula (NGC 7635) is located to the upper-right of M52. The bubble is about 10 light-years across, and is being formed by a hot, young star whose stellar winds are pushing away the gas and dust of the nebula.
A little to the right of M52 is a sparse open cluster cataloged as Czernik 42.
A lot of the Bubble Nebula is not visible to my camera--most likely because the camera still has its factory-installed IR cut-off filter. Removing the filter is supposed to increase the camera's sensitivity in the lower-wavelengths of the visible spectrum.
