Thanks Trevor, this image is comprised of (203) x 30 sec subs for a total of 1hr 41 min 30 sec. I was going for 2 hours until my inverter/power supply started beeping due to my battery power being low and everything came to a screeching halt. I couldn't get DSS to stack the whole image without an out of memory error. So after my 3rd try of making the DSS image box smaller and smaller it finally stacked without any errors.
