ISS and Axiom AX2 Pass (May 21, 2023).jpg
This is the pass of the International Space Station (ISS) as the very bright set of streaks, accompanied by the parallel track of the fainter SpaceX Dragon capsule with the Axiom Ax-2 crew on board as it was catching up to the ISS for a docking the next morning my time. It had launched earlier that afternoon from Cape Canaveral on a Falcon 9 rocket. The Ax-2 was the second private crew flight to the ISS via the SpaceX Dragon capsule. The commander was the ex-NASA astronaut Peggy Whitson.
This was at ~11:20 pm MDT on May 21, 2023 when the ISS started its pass, followed 4 minutes later by the Axiom craft chasing the ISS in a lower orbit.
The Moon and Venus are setting in the northwest at far right. The ISS and Axiom emerged out of the west and rose to pass high across the south as they headed off to the east. The ISS was visible right from the horizon, but the Axiom capsule became visible only when it was much higher.
Other satellite trails are in fhe sky, including one bright flaring satellite at lower left.
During the roughly 7.5 minutes of accumulated exposures the sky rotated around Polaris at upper right to create the star trails. Clouds also moved and blurred.
This is a stack of 34 x 12-second exposures with the TTArtisan 11mm full-frame fish-eye lens at f/2.8 and Canon R5 at ISO 3200. The 1-second interval between exposures created the gaps in the satellite trails. I made no attempt to patch the gaps, as they provide a visual indication of the changing apparent speed of the ISS in particular as it goes across the sky.
