You're safe now.  Noddy and the Auld Lang Syne cats have gone!  ;D

I had a lovely time entertaining my cats with "Auld Lang Syne cats". Nemo still can't figure out where they are....... he's a boy, what can I say.  :)x

cool!! beat our dodgy attempts...

We have a webcam on top of the University observatory here at Birmingham try to look do night snaps shots, it was a testbed instrument for a more advanced system (one to look at the sun, for sunspot, and a meteor hunter; we were going to get the students to build)... but here is what a typical night looks like - http://www.sr.bham.ac.uk/observatory/download/webcam/cam3/20081130.avi - guess what the main problem is... and it starts with a blasted C....

Plays here, Sam, though with a strange texturing for most of the file (vertical lines).

yep, that's a problem with the processing we do on the files... we still have some issues to overcome on that...  in some of the others you can actually see the sky rotate.. look at the stars moving in this one: http://www.sr.bham.ac.uk/observatory/download/webcam/cam3/20080424.avi (not the bright pixels but the fainter ones, you should see the plough (or big dipper) at the centre and that rotate around)

Sort of. You need to know what you're meant to see, if you know what I mean.

yeah, I understand what you are saying... you should see something like this shape, http://en.wikipedia.org/wiki/File:Ursa_Major_constellation_detail_map.PNG, move around... though its not as spectacular as the first link - I'd stay with that for the wow effect :-D but one day we might be as good!
