Satellites and Domes
I took a timelapse of the northern sky from the porch of the Spacewatch 1.8-m telescope and got lots of satellites as the morning twilight was about to start. In this view a bright satellite glints sunlight (it may be an Iridium flare - it must have been pretty bright) as another one runs almost parallel to it almost straight over the Kitt Peak 4-meter Mayall Telescope. Also visible is the Steward Observatory 90 inch Bok telescope dome and the Spacewatch 36 inch dome in that order from right to left. Low in the sky to the left is the planet Jupiter setting in the west in the constellation of Gemini. Near the top center is the Big Dipper. This image was taken with my 10mm fisheye lens on my Canon 70D and an exposure of 30 seconds at f/2.8, ISO 1600.
