I cleared more of my eastern sky of blocking tree branches and waited until another clear morning.  On Tuesday, October 15th, 2013, I got my chance to image Comet ISON again.  It looks larger to me than it was a week ago.  I used the same sub exposure time but with more sub-images.

Here is the “star-streak” version of the same data:

And, for good measure, I did a 2x Drizzle process with the subs and then a rotational gradient filter in IRIS to produce this image showing what is possibly jet-like activity from the comet’s central condensation:
