Description

I've been lucky enough to observe the comet visually in 8x40 binos a couple of times. It's been very faint but easy(ish!) to spot each time.

This was really fun to image, with just a few seconds showing the comet nucleus and 60s showing a clear shape with the coma and very faint tail.  

The moon was quite bright and washed out the sky a little but conditions were better than the night before (28th) where I'd taken some data that had clouds all through it!  These are slightly cropped images from ~430mm focal length so a little close and not showing the full extent of the tail.  I was thinking of using the RedCat but wasn't sure about an LRGB workflow for this.

A little poor framing perhaps on my part to chop the dust tail but I'd hoped for as much fainter ion tail as I could get.  Thanks @Thilo  for helping clear up the tails for me - really appreciated.

The main image here is a composite of the star field and comet stacks. 
Revision B is the comet registration option within AstroPixelProcessor - it gives a great feeling of movement in the image and is very easy to use. 
Revision C is a 60s sub, resampled to reduce noise.

Thanks for looking.
