Hi All,
Imaged this tonight.
1min exp.
I took 5 images 1 min apart and made a small Mpeg, showing its motion but couldn't upload it.
Any ideas?

I found I was able to attach a small animated GIF file. It even shows the animation in the thumbnail.

Ok thanks edwardsdj.
I'll give it a go.

Good one Jeff.

Hi All,
Improved Video, without the 'camera shake'.

Well done Jeff.

I got his last one from last year earlier, you really had to strain to see it!!

Where is this one in the sky? It's full moon, so it might be a bit more difficult, but I wanted to try out an OIII filter to see if I can improve contrast.

Cheers
Stuart

It's amazing that you've been able to capture the movement of the comet Jeff

Hi Stuart,
I imaged 2008A1 last night under full moon.
Might as well chase bright comets.

Here is a copy of a map generated in Guide 7 for the next days. The centre of the field is marked at the bottom left.
Other details can be found at the Minor Planet site.

Well done Jeff, a great capture and animation.

It sure is faint that's for sure.

Cheers

Gee nice one Jeff
So thats a completely unfiltered luminance series of shots?
Gee mag 14 is faint indeed.
I wonder if I should try for it with my Qguider cam? Obviously I wont have a chip temp of -10 deg though lol.

Thanks All for the positive coments. I'm suprised that more comet/asteroid movies have not been posted.

The images were through the IR blocker.
I didn't think 14 was faint. I think it gives a target for the deep skyers during light of moon. I've watched R. McNaught use the 40" during full moon to image asteroids around 18th Mag.

However, with some dark sky I will try for 2006 McNaught currently around Mag. 17.
