This ISS pass was at 07:28 on the 15th January 2016. I struggled with balancing a long enough exposure for the ISS to create a trail without the ever brightening dawn over exposing everything. The sixty short exposures were stitched together in Photoshop to create the ISS long trail. The other two small trails evident in the image are the star Arcturus above the ISS and the planet Jupiter below.
