So, now I am very frustrated. I took my brand spanking new CED M2 to the range today and tried to get data. The wind was blowing and I was having trouble keeping the tripod upright. At one point, the two sand bags were not enough. Winds were blowing at up to 25 mph, with sustained winds of 3-5 mph. Above this base, it was very gusty. The wind never went below about 3 mph.

Even when the wind was calm, say under 5 mph, the skyscreens were wobbling all over the place. They are very large, very heavy and shake a lot in event he lightest little breeze. I suspect this was preventing the acquisition of good data.

Do I need to build a tunnel to house the chronograph? Do I need to stabilize the skyscreen in some way?
