The reflections are created by the light on the drone, you can turn on the landing light also if you need more light. Exposure time are between 3.5 and 5 minutes depending on the waypoint count and speed. All but one are under 100 waypoints and the Eagle is 120. I have refined a couple to smooth them out and going to run them tonight.How did you create the water reflections? Also, how long were your exposures?......the star trails are pretty long.
