G'day Troy. I really appreciated your input on the other post mate. Thank you.
I want a faster lens so I can cut down my exposure time, therefore cleaning up star trailing and also noise. When I am doing time-lapse, I am coming home with 800 to 1200 frames. With shorter exposures I will have more again. I really don't want to be messing around too much subtracting darks from this many frames.
