"1100 Miles in Orbit," Middleboro, Massachusetts |
On Sunday, April 3, 2016, the ISS was expected to become visible in the northwest at 8:41pm in southeastern Massachusetts for about five minutes, moving toward the northeast and not too far from the horizon. I chose Pocksha Pond in Middleboro, Massachusetts as my location. There's a narrow road, Long Point Road, that divides Pocksha Pond (to the north) and Great Quittacas Pond (to the south). Several large blocks of stone descend from the roadway into the water on the northern side; I set up my tripod and camera gear on a stone just a few inches above the water surface. It was a cold night (around 35 degrees F) and somewhat windy, but not enough to affect the stillness of the camera shots. I took some test shots using a Canon 6D and a 14mm Rokinon lens at f/2.8 aperture. I decided upon a 200 ISO setting and a 25-second exposure. Once I programmed an intervalometer to take 25-second shots with a 1-second interval between them, all I had to do was sit and watch. You might ask why I didn't just take a 5-minute exposure; the two reasons are increased image noise and an overexposed shot.

Once the ISS disappeared, I packed up all of my gear and made the short drive back home to my desktop computer. When I pulled up the raw images, I knew I had captured something truly great. The post-processing involved four steps: 1) using Adobe Lightroom to make corrections for contrast, lens aberrations, etc. in all eleven images; 2) using Startrails to "stack" the eleven images of the ISS into one shot; 3) using Adobe Photoshop Elements to process the stacked image [mainly to clean up the image due to the unsightly light trails of a lone aircraft]; and 4) using Google Nik to create a gritty, painting-like look. Here are some visual examples from each step of my process:
A single frame; note the edges need to be cropped due to lens corrections; also you can see below the ISS trail there is an aircraft's trail |

I could have stopped with the last image above. It's a very clean photograph. But I wanted to add a gritty, painting filter with some subtle adjustments using Google Nik. The final result is what you see at the beginning of this post and what hangs on the wall in my favorite coffee shop!
In this photograph, I believe there are a few points upon which you can focus, all of which add to its unique beauty (in my interpretation): The building and surrounding trees are part of the Island Terrace Nursing Home. The nursing home creates some light glow in the sky, but it also shines some distinct lights upon the water surface. The trees ground you to the earth in the photograph. Several wispy clouds along the horizon add some movement; they're sort of dream-like. You can see star trails in the night sky that draw your eyes to Polaris, the North Star, around which all of the stars appear to revolve. And of course the International Space Station's light trail is the central theme. There are small gaps in the light trail of the ISS, due to the one-second gaps between each 25-second shot; I'm okay with those gaps because they show moments of silence from the camera perspective. Finally, there's the added gritty filter - my own personal artistic mark.
The title "1100 Miles in Orbit" references the distance that the Space Station traveled in its orbit around the earth during the time that it was visible. It is a fast moving technological marvel that won't be around forever. Russia, the United States, Japan, Canada, and the European Space Agency all have collaborative stakes in the International Space Station. We're guaranteed to see the ISS in the night skies until at least 2020. Beyond that, its expectancy is unknown. For now though, we should appreciate it -- scientifically and visually!
