About this image

I did a long run on the comet last night. The magnitude was fairly constant through the night but the coma expansion was clear. The image is a log stretch at 0.54 "/pixel showing the asymmetrical coma. It is now filling a 32 arcsec diameter photometric aperture. A rotational gradient shows apparent jet activity, some of which can be seen in the log image. I'm always very wary of this kind of processing but the signal is strong. Hopefully people with larger telescopes will confirm this.
