[althecoal]

Ok out of 10x 25s subs and 10s delay between subs so about 5-6 minutes from start till end ,,,all of these subs has this streak of light going right to left and upwards from the bottom right to top left,,, any ideas? could be high altitude satellite but i dont know about much about satellites so just guessing..

Btw this is in LEO...

As you say, probably a high altitude satellite. Leo is close to the celestial equator, where the geostationary satellites are located, and they often appear in images in that area. If it was an asteroid it would have to be a very close one to be moving that fast, and at that magnitude would have been detected by now.
