G'day all,
Nothing fantastic this time, but finally got around to processing an image of C/2007 W1 Boattini from 1st May:

Comparing it to my older image from almost a month prior is interesting:

(click through for full images, unsure why the image resizing of the thumbnail is messing up on these)
When I subtract one from the other it's quite obvious that earlier on it had a more comet-like shape, where as now it's more circular. Perhaps that's just indicative of the central region seeing as I'm at narrow FOV, hard for me to know if there's more tail continuing out at the moment.
Roger.
