Novice Challenge

ISS Solar Transit, 15th July 2022, but only just...


Recommended Posts

I set out today to capture a solar transit of the International Space Station with my Coronado PST. It was a close pass, with the station only 485km distant and with an angular size of 57".

I thought I'd aimed it correctly, but clearly not. The ISS just appeared in two frames, clipping the bottom left-hand corner. Better luck next time. I find it really difficult to orientate yourself with the sun and predict where the ISS will go, even with the information on transit-finder.

Coronado PST, TAL 2x barlow, ZWO ASI290MM cam. c0.6ms exposure, c 50fps.

You did very well to capture that..

Many thanks!

It won't have been the same transit you saw. As you see here, the transit path was only a few kilometres wide, lasted less than a second and missed Kent!
