Details:
And yet another solar transit by the ISS. This time I was not sure that I could get to the location predicted via CalSky, so I did not have great expectations…
But, luckily, after going a bit over the speed limit ;), I found myself in a nice field of…green stuff. Nevertheless, this type of astrophotography is never easy, so a few clouds had to cover the Sun just 5 minutes before the event…
Again, luckily, the clouds dispersed 1 minute (!!) before the transit, so that I could focus and wait for the black silhouette of the ISS to pass. Seeing was terrible, but the pass was favorable with many details of the ISS structure well resolved.
I might have been speeding on the roads, but it is nothing compared to the speed of the ISS in orbit…the transit lasted about 0.5 seconds…
The setup: homemade 150mm F/5 refractor (iStar lens), Herschel wedge, 2.7x APM coma correcting barlow, Baader green filter, ASI 174MM.
