I'm completely new to this stacking thing, i've just started tonight with some star trails and have been reading through this thread alot and darks, flats etc come up alot.

Hi Lukeness!

Have a look here for some rough info http://stargazerslounge.com/topic/210376-simple-explanation-of-lights-darks-flats-and-bias/?p=2245240 .

Each frame type is sort of a topic on its own to be honest but the above thread should get you started !
