The obvious green coma outer part of the coma is gone but there is a brightening off to the south. There is also an obvious extension of the coma to the south and when I over process the image the ion tail is obvious... will post later.

Still waiting on this ion tail DaveG. Hurry up and finishing processing - its now 10th.

Love to see it pleeease!

Beaut photo by the way, you obviously put a lot of work into this one.

Have a look at this though. It puts us all to shame, I'd love to know more about the exposure details:

The comet tonight looked truely remarkable in 15x70 binos. Didn't bother trying to photo because of winds and cloud though. Its getting bigger all the time and the mass of the outburst must now be occupying an area bigger than the sun. Truely a remarkable event, is there any news yet from Nasa on Hubble or Cassini data on this? :

Dave,

Who said astronomy was a hobby, sometimes you have to work at it :lol: . In the Dob is it not starting to blind you?

I'm almost ashamed to say that I haven't seen in in the Dob for over a week now, just no opportune time when i was free.

Hi Folks

Heres the comets tail before this disconnection event that occured over the 8/9th. I have some imgs from that night if they show this event will post them.
