Something doesn't right to me. Shouldn't the streaks vary more in their length? They all seem really similar, which given the set time of 8 seconds would mean the speed to relative distance relationship would have to be near constant for all. Some of the ones on an approaching/departing path seem to show a small variation. But are none of these on an elliptical orbit with the appogee in view? Should have a much bigger variation, I would think?
