canon ixus 400 vs canon powershot a80 - simple astrophotography?

Hi everybody,

Has anyone any experience using either of these 4MP cameras for simple
astrophotography? If so any feedback would be appreciated, thanks.

I get good results with the 2 Megapixel Canon Powershot A60.
It retails for only $230 and it has a great bayonet mount on it.

I dont think the S400 has any manual photographic controls, unlike the new
A80. Control over shutter speed/aperture etc are important for
astrophotography.

The S400 is mostly auto, but you can manually set long exposures from 1
to 15 second with noise reduction.

It also has focus lock which if I understand this right means you set it to
some preset value, then it remains so until you undo that operation. So I
guess this means one can lock it at infinity for afocal imaging? What is
does not have is a threaded lens mount (unlike the a80 which uses a special
adapter that fits to the body) which might be a problem. Also I am unsure
how recessed the lens is, and if that's a problem too.

Thanks by the way for all the replies. If anyone knows of any web sites
showing astro images taken with the S400 or the a80, I'd appreciate a few
pointers.
