It amazes me how much "stuff" is moving overhead, this image is made from a selection of 5 or 6 frames taken from a batch of 40 or so taken over about 90 minutes.
The brightest trails - the 4 parallel lines - are clearly made by an aeroplane. I'm not sure about the rest, probably high flying aeroplanes, or maybe satellites...
There are 7 distinct trails, and I think that the field of View is about 4°.
