Aha! I knew it was something MkIV. Just got back from solar viewing at the Robert Ferguson Observatory, may end up back there tonight after dinner to see what else they're dragging out.

It's the Canon 1D Mark IV

One of the biggest items involved with astrophotography is time. It requires lots of it (both during image acquisition and in post-processing) to produce good images. You also need mother nature (weather, et al) on your side.

Okay, must be the Mk III that I'm thinking of. What's the full-frame one that's coming out soon that goes to ISO 100k or so?

Yeah, there's probably a lot I can do if I just pay a little more attention to the gear I've got.

Hmm... you're waiting for the 5Dmk4 Dan? Heck, I'm still waiting for the 5Dmk3 to be released. The 5Dmk2 has barely been out a year.

This is an incredible photo from the Wired article:

The cool thing is that this specific composition is only using about 100mm (or less) of focal length, and you can clearly see the Horsehead Nebula, among others.

As long as you have a good mount, a good sensor, and dark skies (repeat, dark skies), you can do some amazing wide-field astronomy with some rather minimal focal lengths.
