Close Up of Comet 17/P Holmes 25 Oct 2007

John, how did you see it?, its blanket fast moving clouds here.

I've been running in and out all evening occasionally catching a few minutes of good seeing. Very fast moving low cloud here with slower heavy dark cloud higher up, just getting the occasional bit when the sky is fantastically clear, that wind seems to have blown all the moisture out of the way. I can't leave this thing alone, its fascinating.

Dave Gr,
The unprocessed image of the comet looks alot better to me, more details to look out for if the sky clears.

Guys here's one from this evening;

40x 10sec shots, 5" Maksutov, ATIK16HRC

I wonder if it is misalignment in the stacking?

You could be on to something there Kieran. My hunch is perhaps something like sigma clipping is to blame. I confess I don't understand the finer points of registax. Maybe something in registax is doing it.

Fab shot there Dave.
The detail is great.
The change in size is awesome and you captured it brilliantly here.

Hi
Just managed to get a glimpse of the comet in the 8" before the clouds moved in. I reckon it is very slighty asymmetric. Possibly a line of sight effect-perhaps we will see some sort of a tail appear.
