Malcolm,
I would be very happy with that Jupiter image! Is this also done via the liveview/video mode of the 450D?
I have been considering this as an interim option in that you have a decent cmos sensor capable of taking video (not exactly like the 5xx models but you probably know what I mean
I have a 40D and played with video for a short time and I am seriously considering giving this a go - certainly to try a different angle
With your Jupiter image, if you did use the liveview video, how many frames and which program did you stack with? I have Registax so I might give this a go!
I think the live view "video" mode is worthy of a thread on its own to see if us non ccders can push our existing systems until some more $timulu$ comes along from the boss
(both work and the missus!)
Cheers,
Darrin...
