   This evening the ISS flew across my southern horizon from the southwest to southeast and at its maximum visibility reached around 45 degrees in altitude and got to about -3 magnitude. Its path, as the banner graphic shows carried it past the ‘teapot’ asterism of Sagittarius toward the ‘Square of Pegasus’. I took a series of pictures with my fisheye lens with a shutter speed of 5-seconds, F4.6 aperture, and an ISO of 3200. The path the ISS followed started from behind some trees and then behind my big Oak tree. As it emerged on the east side of the tree it faded from view. Near the top of the picture are the three stars forming the ‘Summer Triangle’ asterism, and on the left side look for the ‘Square of Pegasus’.

   So after the ISS faded from sight I aimed the camera straight up toward the zenith and took a few pictures of the ‘Summer Triangle’ asterism. The shutter speed was 5-seconds, with an F4.5 aperture, and ISO 3200. Two smaller constellations, Delphinus the Dolphin and Sagitta the Arrow are in the picture but easy to see in this cropped picture.
