This blog post contains images from the balloon taken by two of the three Raspberry Pi Zero cameras on-board. Unfortunately the third suffered catastrophic data loss (probably upon landing) and everything on its SD-card was lost. One of the Pi cameras faced outward from the side of the payload and the other at about a 30° angle off of straight down.
About 5 minutes after launch.
Looking at Shoshoni, WY soon after launch.
Totality approaching. Balloon altitude is about 28,000 feet (8500 m).
Shadow approaching on the ground.
Start of totality in the clouds.
Totality.
Shadow receding on the ground.
And in the clouds…
At about 45,000 feet (13,700 m). Temperature outside is about -58 F (-50 C).
About 80,000 feet (25,000 m). -12 F outside (-24 C).
The ground from near the highest point the balloon reached (94,000 feet/28,600 m). It took about 3 1/2 hours to reach this.
Just as the parachute burst. Decent was 27 minutes.
Just about to land. Balloon all tangled up.
A SSDV photo received by the launch team shortly after launch. Some packets lost.
