Hi Ben. The list of mid-year targets you have there look well suited to the ed80 dslr combo (although m83 might be a bit small at that image scale). Other easy targets could include areas surrounding: NGC3579, NGC5139, NGC6357, NGC6559, NGC6729.
Good results are possible with a DSLR if you're prepared to go for lots of subs - have a look at some of these images of mine (all taken with a DSLR):

strongly suggest you look at acquiring a coma corrector if you are considering using the newtonian for imaging. Coma will be quite severe otherwise, particularly with the large FOV afforded by a DSLR.
