You can find 600 individual frames at https://we.tl/t-1o5vYiCHM6.
These are written out as python numpy arrays for 100 frames at a time.
The _t.npy files contain the time stamps in unix format, while the
_z.npy files contain the video frames (shape of 100x1172x1552 at
8bits). I've also included png files showing the astrometrically
calibrated image of each 100 frame set with satellite predictions
overlaid.

Yes, I'd be very interested in that comparison.

They are from the PC clock which is NTP synchronized. Should be better
than 0.1s.
