Details:
I have corrected the animation speed to a more accurate value so this is closer to the real speed) On 2021-10-09 captured 2 #satellites passing through the narrow barlowed telescope field of a 10 inch telescope, actually while tracking the lower satellite. The altitudes of both satellites are very probably different in this case but this may give an idea how a near-collision would look like!
The movement of the lower satellite tells nothing about its angular speed because it is a movement caused by the manual tracking error that is always there. So only the movement of the upper sat relative to the lower sat counts.
