>Damn, I knew that is why I botched my 6-stop exposure at my daughter's graduation!

how about driving for 6-stop before taking the shot a tank with stabilized gun trained to the target. Now the tank gunner has the excuse too.

I shot competitively in JROTC and after, but never out to 1000 yards (914 m), only 500 yards. The Earth's rotation affects your trajectory significantly particularly if you are shooting longitudinally at a target at a higher or lower latitude. The Coriolis effect. I had more issues with varying winds or being consistent across shots.
