> You won;t get many scenic views at night
If you manage to get away from the light pollution (so probably not in the Peak then), the view straight up on a clear night can be plenty. Like most people I live in an urban area and go months on end without seeing more than the Moon, the odd planet and a handful of stars so a proper dark sky is a real treat.

Also may be the best bet for enough of a breeze to keep the dreaded midges off.
In the Peak, the Derwent edges could be worth a look. Back Tor especially. (If you don't mind the scenic view to the East having Sheffield slap bang in the middle of it.)
On the other side of the valley, maybe Alport Castles. It's a very atmospheric place. There's a little birdwatching hut up there that would be horribly uncomfortable to try to sleep in but does at least offer shelter if the weather turns nasty (or sanctuary if the midges go into a feeding frenzy).
There's a long history of folk bivvying in the cave at Laddow. (It's not much of a cave, but a dry stone wall was built some time in the last century to offer a bit more shelter.) It's east (ish) facing, that one, so if you're lucky you get woken by the rising sun.
