These are two images of this tiny and unusual comet, both with its orbit trapped between Jupiter and Saturn and its cryo-volcanic outbursts, with its rapidly expanding coma since the outburst started on 19th November.  I had to capture these images unguided and deliberately with no filter.  The main image is a stack of the first 60x10seconds images of the stars with the comet in that time hardly moving against the background.  The inset magnified stack is all 250 images stacked by hand on the comet and has enabled me to pull out some features in the coma, which in this image appears to have a coma spiralling from the right hand side clockwise round to the lefthand side.
