Brief summary
An opportunity popped up in Calsky, a possible chance for a lunar transit. It was predicted roughly 30mins before sunset, so I did not have too high expectations about the final result. Moon was at 41° above horizon at the time of transit.
Calsky only show the centreline, ISS Detector app show the edges too. Edges I mean when ISS passes close to the edge of lunar disk. This way I could roughly find the place from where ISS wasn't only in front of the lunar disk, instead a bit of both. But I was only hoping for a good outcome, now looking back it couldn't be any better than this!
I had doubts to even have clear sky, clouds were heading toward east leaving nice clear skies behind - but the question was if it clears up in time or not.
It did at the right time, so I could capture the transit which I only saw from the corner of my eyes whilst :) When I watched the recorded video I was jolly happy 😄
Imaging and processing
I took a high frame rate video (around 120fps) with the equipment below. Once I finished recording, I ran the video through a software called PIPP to break it down into individual frames. I improved the frames of the transit in Lightroom. After engancing details I had to crop them to this smaller size so that ISS remains always in the centre of all frames. Then stringed them back into an animation in Photoshop. This is not the real speed of the transit, it happened in a blink of an eye!
