ISS lunar transit animation

Recommended Posts

Hi all.

The International Space station did a transit of the moon at my location this evening. The station was illuminated, rather than silhouetted, and I wanted to capture it as it crossed the terminator. Unfortunately very high winds, terrible seeing and cloud made things a bit challenging! Due to the cloud I could only manage 30ms exposures which, for an object travelling at 8 km/second 'only' 650 km away, wasn't sufficient to freeze it.

Anyway, heres a gif of some of the captured frames. At least you can see the double trail of the solar panels. The ISS appears on 2 of the frames.

QHY5-ii mono cam, TAL 2x Barlow, 250 mm f/4.7 Newtonian.
