I agree, and would love to see your image! I've photographed several but unfortunately never more than two in the same frame. Attached are the same satellite processed different ways from a number of fairly short subs, first stacked on the satellite and second stacked on the stars. Notice the relative brightness differences - in the first the satellite is reinforced, while in the second its brightness is 'diluted' in the stacking process.

Small things amuse small minds...
