So, I was in the middle of my writing and I was trying to describe what one of my characters was seeing/looking at while he was laying down and looking up at the sky. When he's laying down there are mountains "above him" (meaning his head is toward the mountains) and a valley "below" him. How do I describe that he can see the mountains before seeing the expanse of the sky with all of the stars, etc. My initial thought was, "At the top of his vision..." but it just sounded odd. Any ideas?
