I'm shopping for a new, digital SLR for deep sky astrophotography. I have a lot of Nikon accessories but Canon seems to dominate the deep sky. Is there something about Canon I should know?

There are various test in past years that show the Canon
was superior in terms of lower dark current (thermal
noise). Perhaps this is not true of the
latest models, but may have created an early preference for
Canon which they still enjoy. Some references are:

If you are mainly concerned about lenses, note there are various
adapter rings that will allow you to attach your Nikkor lenses
to the current Canon bodies. The adapters cost $20 to $80.
You lose most of the automatic functions, but for astro they
do not matter very much.
