Not wanting to upset anyone but I think it is a meteor shot.
Basically for these reasons:
1. If it were a bright star and the scope slewed it would have left a straight trail and not a wiggly trail. Try it. Also it would have had to
be a few seconds still and then slew as the bright ball would not have exposed hardly at all otherwise.
2. There are trails in the background that are not parallel. If it were trails from an accidental slew these would have been parallel not at different angles. Looks like he caught a few in the background. Maybe fragments?
3. Hot pixels don't look like that or at least not in DSLRs I have used. There usually aren't that many and they aren't different brightnesses as much as those are. They look like underexposed stars. If his camera has that many hot pixels it may be time to get a new camera!
4. I wonder if it was space junk or irregular in shape and perhaps tumbling.
5. Meteor shots in a long exposure are a very common event. Not rare
at all in fact if you image 5 hours you will no doubt have at least several meteor trails in your images.
I'd love to see a bright meteor/space junk. So far I haven't seen a really bright one. It must have been a great sight.
It certainly has captured the groups notice and I am sure Chris is really glad he posted it!
