The answer is gravity! There is a small measure of tube flex, camera flex, collimation movement. All of these tiny little flexes may not be noticeable sub to sub visually but can cause some registration havoc. |

Ha ok, that make sense as the flipped fov wouldn't be exactly the same. I use Prometheus from MBJ (MnT) and that will align about anything on top of anything else with incredible accuracy. That's the only program I ever use to register my stacks of subs.
