Colin, you can get great images from a newtonian but remember you will also need something to guide the mount, i.e a guidescope or off-axis guider with an autoguider camera or illuminated eyepiece. I know that may be a bit confusing, but to put it simply, no matter how good your polar alignment is, your mount will have tracking errors - guiding a mount makes corrections when thing start to go off which allows you to do long exposure photography.

Don't let it put you off though - obviously people are using that scope to get some great images (http://skywatchertelescope.net/swtin...action=gallery) - that's pretty much the setup you're looking at I think
