"Here's a picture I took of the Magellanic clouds nearly 2 years ago with a Canon DSLR camera that was several years old at the time. It is a 15 second exposure unguided exposure at ISO 5000 which is not the maximum ISO possible."
It's just amazing how deep one can get "these days". I've seen recent images with stars down to magnitude 9.5 (dark sky site, of course) with no trails from DSLR cameras on simple tripods and exposure times of about ten seconds.
