Leon I did not see these images before I made my reply in your other post.
It could not be an iridium flare because they reflect the suns light, and are in a fairly low earth orbit.
The Sun would have been on the othe side of the globe at that time of the morning so could not reflect on the satalite, also the streak is very small and not very brord.
It was probably a meteorite or a bit of space junk.
Visual observers see these thing in their eyepieces quite often in a nights observing.
The images are very good, and your time was well spent.
Keep up the good work.
Regards Ron
