ISS over M6


Stephen Cheatley


To take the shot I used a Nikon D600 with a 14-24mm lens set to 14mm f3.5 with an ISO of 250. I took six exposures, each at 30 seconds. Later, I stacked the exposures using Starstax. I then opened the image in Photoshop & filled in the gaps of the ISS trail. The last step was to reduce the long star trails which had resulted from a 3 minute total exposure by blending the ISS trail with one of the single, 30 second frames.

I took this image last summer of the ISS as it passed over Lancashire UK. I thought it would be a good idea to shoot from a road bridge & use the motorway as a foreground, including the light trails. I planned the shot by visiting the location by day, and checking there was a clear view of the motorway. This is the view to the south, so I knew the Space Station would cross the sky over the motorway at a particular time. I checked the website Heavens Above for the details of the pass. I also knew that the ISS would pass into the shadow of Earth as it crossed into the south eastern sky.
