If the exposure was 1/500 of a second then camera "jostle" would
be virtually impossible, as that would mean the camera was
jerked at a velocity of about 0.4 m/sec or about 1 ft/sec. The
Y-shape of the 4th photo red object is not a continuous motion
smear image. The camera motion would have to precisely retrace
one branch of the Y-shape then move back up the other branch
which is patently absurd.

If the 300 mm lens was used then according to Bruce's
measurement the image was only 2.9 milliradians or about 10
arcminutes or about 1/3 Full Moon. That is not a prominent
angular size, and given a 10-second cycle of brightening and
dimming (or rotation where the full Y-shape was only seen
briefly during the 10-second period) then there was not
continuous visibility of the Y-shape.
