Hi All
I thought this was a good example of the effect that troubled early astronomers around multiple timings between different observers. With the unstable conditions I experienced the uncertainty in separation lasts conservatively 45 seconds on the video at my Griffith location and well over a minute I think in reality.
At the egress stage in the afternoon, the conditions had significantly improved and the effect was hard to detect.
Yes me too..at egress I most certainly had the tear drop effect, captured both in white light and in halpha, though not at the extreme focal length you imaged in
