I got a new Canon 450 D for Christmas and I was wondering if you could
give me some basic advice concerning the setting for astro photo?

I have an OPT adapter (cheap black one) and an off axis.Canon T-ring as
well. So I'm able to mount it to my LX 90 8". I am unsure which settings
on the camera to use apart from using Live view Function settings.I
appreciate any suggestions!

I have been playing around with my ETX 125 and my Canon A560 camera to
slowly learn the how-to's and maybe take some good astro-photos.

The main problem is the very short exposure time allowed by the camera
set up. I have found that the CHDK software has some scripts that
provide 64 sec exposures. This helps, but I would like to get to 12 or
15 minute exposures.

Does anyone have an idea on a CDHK script that gives such long
Mike here: For long duration exposures, keep in mind that precise tracking will be required. And the digital noise will increase as well. Usually it is better to keep exposures short (seconds to a couple of minutes), take multiple images of the object, and then stack them. It is more work of course but the results are usually better. Of course, if you are like me, you want to get the maximum out of a single exposure. I rarely stack my images.
