Probably my favourite shot from my Pi weather balloon flights, this one was taken at 38.9km altitude with the Pi camera and a model A running from 4 Lithium batteries. The view is south-west from high above Swindon, looking out over Devon and Cornwall.
As well as the full resolution stored images such as this one, some smaller images were taken and transmitted "live" during the flight.
Here's the Pi with camera, GPS and radio shortly before the flight (pic not taken by a Pi):
