We've put together a list of some common and some not-so-common targets for astrophotography in Autumn over at
http://www.atik-cameras.com/news/autumn-astrophotography-targets/If you have any more suggestions (and I'm well aware there are plenty more!) just let me know and I'll add them in. Likewise, if you have any tips for imaging the ones already there, I'd love to hear them, or you can always share your images over in deep sky board.
Clear skies!
