Oh and if you want a Canon10D to play with, I can lend you one, it is gathering dust on the shelf. The D7000 has exceptional low noise performance, but I agree there are more apps that support Canon. Depends if your main focus is AP or traditional photography. I used the Nikon for both, and figured one day I'd end up getting a dedicated astro CCD anyway (which I did a month or so ago), so I went with the Nikon with that in mind.
Yeah, Ken is a fruit loop, but every now and then he makes sense
