ISS over Kitt Peak
These first 2 images are 30 second exposures at f/2.8, ISO 400, taken back to back. The first shows the ISS trailing over the planet Mars while the 2nd it is above the star Arcturus. The Moon is in the upper right corner. The building is the Spacewatch 1.8-m dome. All the images in this post are taken with my Canon 70D and a 10mm f/2.8 fisheye lens and identical exposures.
Turning the camera to the right, the ISS is now setting into the northeastern sky over Tucson which is lighting up the clouds a bit between the building and the rock.
The ISS is still visible as a dimming trail in the clouds above Tucson in the lower right edge of this image. The domes visible from upper right and then across the bottom of the frame are the 1.8-m Spacewatch telescope, the 4-meter Mayall Telescope (the largest on Kitt Peak), the Steward Observatory 90 inch Bok Telescope, the Spacewatch 36 inch telescope and the rolloff roof of the Super LOTUS telescope. The Moon is just barely in the frame at top left and you can also find the Big Dipper near top center and the planet Saturn above the Super-LOTUS dome at the left edge of the frame.
