Thanks, I appreciate that, I'm guessing it starts to become very easy to recognise constellations by eye after a while, hopefully I'll get there soon!
I stupidly forgot to use Star Walk (I'm guessing this is also a very beginner thing to do) to check where it was looking when I took the photo, instead I went home and tried to remember the direction.
Anyway, for a phone on what was still a fairly cloudy evening and only 5 minutes out of Aylesbury I'm happy with the results.
This is what I thought I was looking at (forgot to mark it in original photos), I suppose I wasn't far off of where I was looking from memory with perseus being just above.
