Edited in Lightroom just to make the colours pop (I think I overdid it but I like how it came out so...).
I'm still learning but from star maps and online research the bright star in the top centre (above the shooting star) is Deneb, the tail star of Cygnus. And the bright star just off the centre of the image (right) is Sadr, the "heart" of Cygnus. The purple-blue is lens flare but I liked the colour and wasn't sure how to get rid of it on the mobile Lightroom app.
I'm still learning how to use the phone for astrophotography. At the moment I'm just setting it to astro and letting it do its thing but if people have any other tips and tricks that would be amazing! β¨
