About this image

Graham writes the following about this image:

M78 is the brightest diffuse reflection nebula of a group that belongs to the Orion B molecular cloud complex, but with an apparent size of 8 x 6 arc seconds it is a something of a challenging target with my equipment.  Notwithstanding, with the mono CMOS ZWO camera and the opportunity of obtaining increased integration times I considered it worth a try and was not disappointed with the outcome.
