1 Andromeda Aircraft
Here is an interesting sub frame of an aircraft crossing the Andromeda Galaxy.
You can clearly see the tail plane lit up alternatively from the left or right depending on whether the port or starboard strobe is flashing.
Also the trail stops part way across the frame indicating that it happened in the last second of the 120 sec exposure (nearly missed it)
you might also notice the starboard white trail is also slightly longer, this is because as the shutter effectively closes from the base upwards
it covers the orange port trail first and the aircraft fly's further before the starboard trail is covered (must be a way of working out how fast it's going)
Quite interesting from a frame I was very close to deleting.
