VdB 152 : reflection nebula in Cefeus

My initial intention was to image with Luminance binned 1 x 1 and R, G and B binned 2 x 2, but by mistake I did the luminance subexposures also binned 2 x 2, which results in reduced resolution, but at the same time increases the signal in the subtle areas of the nebula.
