I don't shoot one of these every day so forgive me if I am hasty this once:
lower left to upper right and took about a second. There was a very brief persisting train also of 1 second or less. It dissipated very rapidly.
I took 25 exposures of 30 seconds each with readout times of approx 30 sec. So Vicki and I watched for approx 30min with 12.5min of exposure time. After a quick look (now) I could only see the one that we also saw visually. No moon, but scattered light from villages around the shore of Lake Simcoe - we were at the foot of Woodlawn - and there was much cirrus, not a photometric night.
