Are those all shooting stars on the right (being as you haven't got long star trails), and what are the straight lines of light that appear to be down in the valley?
Generally loving all these shots - looks like superlative weather for photography.

traffic I'm sure of
shooting stars I hope, not lens scratches!
but what I'd really like to identify is the coloured flying saucer at 116˚ from Beinn à Chrulaiste at 1803. It’s in RAW file, not an artefact and in another shot 53 secs later.

I tried a night sky app, but couldn't understand it.

Hadn't realised there was such a straight bit of road - which explains the straight lights - the UFO - I presume you mean the slight streak well above and slightly left of the Buachaille - I'd have presumed satellite but I couldn't see (Heavens Above website) any obvious contenders at 18:03 on the 9th that would be visible to the SW. Where is it in the shot 53 secs later.

hi Michael in exactly the same place a minute later. It's clearly rainbow coloured too. I asked the same question in photography forum, if you're interested. Thanks
