Interesting .... so from experience .... how many "lights" can you get away between "darks" and still get good noiseless stacked images post processing using a 40D ?

How does this change with exposure length (of each "light" / "dark") ? with effective speed (ISO) ?

I know I have a lot to learn about this digital imaging "black witchcraft". Film imaging was heaps simpler .... you took the battery out , aimed , focused , set the camera to manual , and pressed the T button (if you had one) or the pressed the B button and locked the cable to down until you were ready end the exposure , at the end of the session or roll of film , you took the roll out and gave it to photolab to process and print .... nice !!!
