Please explain?
The other night while visiting my in laws semi rural property on the outskirts of Melbourne, I took a few widefield shots by just sitting the camera on a fence post and aimed it at the night sky. I was using a 50mm lens on a DSLR and exposure was 8 secs, f2 @ 1600 iso.
Upon analysing the shots, I noticed these strange wavy trails in sections of the frame. Having taken the shots not long after twilight ended, I wondered if they could have been a flock of birds lit by the setting sun or insects, or space debris, or fragmenting meteors, or visiting aliens? They appear in several of the shots I took but only in the same section of the sky i.e. just above Orion.
Has anyone seen something similar to this before or knows what could have caused these random trails? I'd be interested in suggestions.
