Well, well, well; what I hadn’t anticipated was the frantic pace set by this 70m asteroid, as it zoomed through my field of view! Here is the trail, captured on 15 frames of 60 sec exposure each, with a gap of approx 26 sec between exposures.

Hi Dennis,
Beautifully captured! Well done.
I used to keep an eye on the NEO list on Spaceweather too a few years back and I've caught
a few on modified webcams.
One of my easier ones was Toutatis, simply because it was due to
go right past Alpha Centauri, so there was no chance I could miss that
by imaging the wrong bit of sky!

It was about mag 9, but because I was tracking the stars and not the
asteroid, same as yourself, the object is dimmer and , of course, will
be a trail.
The only way I could see was to do an EXTREME histo stretch and
make it a negative.
You can just make it out, a very faint grey line.
(not to be confused with the paste artifacts around the arrows )
Also, because of the stretch, you can see the dark holes as well.
regards,
Steve
