Stack of three images, 15 seconds each, ISO200.
Canon 40D on a C9.25 with 2x TC, yielding a focal length of 4500mm @ f/20.
Done more as an experiment to see if I could guide at this
focal length with the Q-guider and the off-axis guider.
Lotsa potential here for M27, M57 and other such objects.
Lousy seeing (2/5), light pollution. Taken 2 March 2008.

taken a few years ago with a different camera.
