Description

Had hoped for much more data, but shortly after having everything set up and taking some test images I realized my main battery was not working. So I was not able to fully power everything (laptop, dew straps, 1600 camera for cooling, etc). I managed to get 10 2-minute subs in L, R, G and B before calling it a night. Wish I had more data, but happy with what I got.
