FMO through the Kepler Field
You take 20 images and you find this in the 20th image and it wasn't in the 19th and of course there was no image 21.
Fast moving objects are nearly impossible to measure (in this case don't know which way it was going). You can try cutting it in two with pixel math and taking three points with timings as the start, midpoint and end of the image - but that assumes you know which way it was going.
In this 30 sec image it has moved about 200 Pixels.
Always a possibility it is a satellite but the speed and angle do look ok for a close approaching asteroid.
