My Ixus and stars in the sky

Hello,

Where can I find info on utilizing chdk on my Ixus 860 IS to photograph parts of the sky?
I was in Australia and noticed the clear skies and amount of stars that could be seen. I experimented a bit with longer exposure times but need some better guidelines, tips etc.
Any ideas?

Also one thing that came up while trying out longer exposure times:

Can chdk firmware give a signal (audio but also visual) that the exposure is done?
Is there already a setting for this?

I think we have script commands or at least C functions for playing system sounds nowadays, but doesn't your camera make a noise unless you disable it? Or does it sound only when you press instead of after it's done exposing?

I do get a sound when the Ixus 860 starts an exposure.
I don't know how long an exposure should be when trying to capture the stars but at the end a beep would be nice.
Can I do that somehow?
Or is it a new feature?
Or is it pointless (at least for stars) because of the lack of zoom on the 860?

Comments are welcome!

In scripts you can do it.
In normal interactive photography you can't, but I suppose it would be possible to add a new feature for that.

Where do I post to ask for such a feature addition?

But how do I get the best results from this small cam when I try do picture some stars?

I do need a stand.
I do need the remote cable.
Right?

But then?
What other settings would I use?

Ever heard the term "Trial & Error"?

Only advice which crosses my mind: Disable the IS - it will cause "shaky" images in long time exposures. Everything else is up to you. Just test for yourself.

Edit: Oh, and you dont even need a remote cable, as the small shake caused by pressing the trigger wont be visible in long time exposures.. Using a tripod is crucial of course.
