Starry, Starry Night

The orbital altitude of the International Space Station varies between 310 and 410 kilometres.

The ISS is maintained in a nearly circular orbit with a minimum mean altitude of 330 km (205 mi) and a maximum of 410 km (255 mi), in the centre of the thermosphere, at an inclination of 51.6 degrees to Earth’s equator, necessary to ensure that Russian Soyuz and Progress spacecraft launched from the Baikonur Cosmodrome may be safely launched to reach the station.

At these altitudes it’s possible to take some really hot daytime photographs of the Earth and plenty of really cool night time exposures of the RGB [Red-Green-Blue] fluorescing oxygen in the upper atmosphere at altitudes between 100 and 300 kilometres.
