While imaging tonight I've just taken an image which I though had caught a plane flying through it. Fair enough, but I've had three subs in a row with similar streaks (though not quite the same angle). Now I'm thinking they might be reflections in my AO unit, though I image at this location regularly and I've never had anything like this before.
The sub before and after these three has no weirdness.
Also I recon I can make out a plane engine in the top right corner of one of the subs, though I'm probably seeing things and it does look like it's not quite right given the angle of the streaks...
Thoughts!?
