I thought I should take Jacques with a longer focal length than I used on August
05 with the Hyperstar, so I imaged it here with my 100mm f/9 refractor at prime
focus with a Canon EOS 400D (as it's inconvenient to remove the QHY8 CCD camera
from the Hyperstar).

A couple of things went wrong with this image. Firstly the exposure I chose was
too long:  there is noticeable drift of the comet in 2 minutes at this image
scale, so it is not as round as it should be. Secondly, it clouded over after I
had only got 6 subs.

I have tried stretching the image and inverting it, as I did before, but there
is no evidence of a tail here at all (though this is a much better calibrated
image than the Hyperstar one).

Processing was in Nebulosity 2, and Photoshop CS4 using GradientXterminator and
Neat Image plug-ins.

A very nice comet, it was just visible in 10x50 binoculars from my site, and in a 100mm OG it was a fine sight.
