Like many others, we sent up a weather balloon to observe the 2017 solar eclipse. The balloon took a few great pictures of the shadow cast by the moon on the earth! A link to an album with more photos is here. The photos below were taken with the Xiaomi Yi action camera, which is a great cheap GoPro alternative. We also sent up a Samsung gear 360 camera to take panoramic photos, but it was mounted outside the insulated payload compartment and stopped functioning before the eclipse was visible.
