I'm not much of an observational astronomer - but using iTelescope scope 11 - I think I caught motion in ISON over 19 hours.

And another observation. 5 images of 500sec exposure with iTelescope scope 5.

Comet ISON has a stubby tail by now. Here's an image from last night (Feb 9.2 UT) with the 1m SARA-N remote telescope at Kitt Peak. This was a 5m exposure in red light, about as long as will not show obvious trailing from the comet's motion. Incoming!
(I'm on the southern counterpart in a couple of nights and there are a couple of comets I want to check on from that hemisphere).

Great work again Doug, really impressed with that. Looking forward to more of those as ISON warms up...
If anyone is interested, I've interviewed Nick Howes, a professional astronomer involved in studying ISON (and PANSTARRS) on my "Waiting for ISON" blog. I think it contains some fascinating insights into the life and work of a professional astronomer. http://waitingforison.wordpress.com/updates-and-images -------------------- |

Not ISON but I saw Comet PAN-Starrs briefly today through 8x40 binos. It was pretty dim, but a tail was discernible. It does not look like the images you see on the web though.
