About this image

I took a series of images to stack but this single frame i thought was quite nice with star colours and a possible meteor. So here it is dark subtracted and flattened in Astro Art 5.  The mag is about 10.  There is movement in 104s which is causing some smearing of the coma.  Motion is towards the upper left, the bright star is zeta Cep mag 3.5, and the field about 0.8 x1 deg
