Edit: I wanted to add: I’m really new to astrophotography, could you share which Bortle scale the spot you took this is? It could help with the expectations for what I can get from my surroundings :)
The spot is a Bortle 4 to 5 according to the map, nothing special but it's only a 20 min drive and has no nearby light sources, offers decent protection from the constant Aegean summer winds as well.
My advice is this: Bortle + Drive time + terrain difficulty= X, solve for the lowest possible X and only go to really remote and dark sites when you're sure you've got the shooting process dialed in.
Generally any moon less night under Bortle 5 skies or better yields great results.
