About this image

Took a long series while testing the autoguider.  Transparency was 3/5 but its reasonably dark here. The nucleus/coma is bright and difficult to extract. The main image is 5 x 60sec,  but the inset is 1 hr (stacked 60 frames on the comet) and binned 3x3 in AstroArt with a gradient filter applied.   There is a suggestion of tail detail which i was hoping to pickup more easily.
