Last weekend, 23 September 2017, was the last night of the 2017 Flagstaff Star Party<\/a>. This is the fourth year the star party was hosted in the middle of town at Buffalo Park. This image was shot while I was assisting at a Night Sky Photography Workshop led by <href=”http:\/\/www.stanhonda.com” target=”_blank”>Stan Honda. It is a composite of nine exposures that show the International Space Station cresting the southwest horizon before fading into Earth\u2019s shadow toward the top of the frame. The setting moon casts a glow in the trees to the right, while the lights of downtown Flagstaff, a little over a mile to the south, light the horizon beneath the Milky Way.<\/p>\n

Images were shot as part of a 270-image time lapse. Each exposure was 20 seconds in length with a 4 second gap between exposures. I selected nine sequential images where the space station was making it\u2019s appearance. I stacked these images in Photoshop and masked the the ISS streaks to a single star field. I selected and masked in the best foreground of the nine images to complete the image.<\/p>\n

The time lapse shows how busy things were at the star party as the Milky Way tilted overhead.<\/p>\n
