I built and flew both Camroc and Astrocam. Did not get any pictures with Camroc. I got a lot of pictures with Astrocam, a good many of them blue sky.

I never got the full 110 cartridge full of pictures. As the article implies, any model rocket flight had a decent probability of either catastrophic failure, or being impossible to retrieve. Get 6 or 7 flights on a cartridge, the temptation to develop it was too much.
