So, a disagreement. My argument is based on the simplest trig required to explain it.

Where I might be wrong is the estimate of the streak length. Nevertheless, that streak length
will not matter for a given focal length, whether the sensor is a crop on or not. Just the field
width is different.

Anyway, AK, I couldn't see in your reply where you showed that the sensor size does matter.

On the matter of the bridge, are you saying that it does not appear to have moved the same
distance as the other streaks? I think it has.
