Let the show begin! With all our reports and images of Comet ISON being in outburst, this latest image from astrophotographer Damian Peach shows just how much activity is taking place in this comet as it races towards the Sun. “Hard to believe this is the same comet in my last image of Nov 10th!” Damian said via email.
ISON’s tail is suddenly full of streamers and features not seen before in this comet. At less than two weeks to its close encounter with the Sun on November 28, only a short amount of time will tell us if Comet ISON is just beginning to show off its brightness or if it is beginning to break apart.
The views here are through good quality telescopes. It is just now becoming visible to the naked eye, looking like a faint smudge at about magnitude +5.5.
Below is a “negative” view from Damain Peach, as well as a variety of views from Joseph Brimacombe and others that are coming in:

If you haven’t seen the comet yet, you can use this map to track it through the weekend as it zips quickly through Virgo. The map shows the sky facing southeast just before the start of morning twilight or about 100 minutes before sunrise. ISON should be plainly visible in binoculars in a dark sky.

And for comparison, here is Damian Peach’s previous image from Nov. 10:
