Please post the entire log and the Plan. In order to find where things are confused, we need to know where your observatory is, what your targets were, and all of the things that led up to it. I can then reproduce the run here in simulation and see what the conditions were.

The wait during the period from 15:00:23 to 15:02:20 should also be done with the tracking off. It just doesn't say that in the log. And which image, and at what time, came out streaked due to the mount not tracking? The pointing image after the flip? Is it possible that, instead, the mount was not yet finished slewing, or had not settled down after the slew that flipped it? Did it actually flip at that time? Seeing the remainder of your run in the log will allow us to tell. Please attach these files <-- link to attaching instructions
