No scope used, just max zoom through the default lens of the Canon S5IS.
I mounted the camera on top of my real scope, just for the tracking.

Yes, longer exposures would be great. I only finished building my observatory recently and my polar alignment still needs some work. I found that I still get some drift if I expose more than 2mins when fully zoomed in with the S5IS. Easy to fix though, I just need some clear nights... Fortunately the weather seems to have improved here, finally

Thanks Yes there's lots of noise still. I will take more frames and see what happens. And will get that polar axis aligned.

I'm really only playing around with this basic Canon cam as something different until I buy a proper CCD next year. Thinking of the SBIG ST8300M or a QHY9/QHY11, both look like excellent options.
