ISS Solar transit with the Coronado PST

[lukebl]

After a night not seeing many Perseids, I scooted up to North Norfolk and captured this transit of the ISS with my PST Coronado. The path of visibility for this transit was only 6.5km wide.

The weather wasn't promising and at the precise moment of the transit, clouds rolled across and the image went virtually black, so I assumed that I'd missed it. However, on stretching the image, I realised that I did manage to capture the transit.
Coronado PST, ASI290MM cam, Exposure 0.88ms, 23 frames per second.

On this transit, which took just 0.66 seconds, the ISS had an angular size of about 50 Arc Seconds and was 513km distant. Other upcoming transits near me have the ISS at 1416km distant and only 20 Arc secs across
