The exact set up I have used to record the event (photo above was taken in UK)
Skymax 90/1250 MC and an ASI120MC cam
|Composite photo of six frames of ISS and the stacked Saturn frames (photo of Saturn at bottom of this post)|
Before I actually traveled, double checked the app called ISS Transit Prediction just to see what if.. than realized ISS might transit the ringed planet. But I was very sceptical (coming from London lol) as always, you never know the weather and other circumstances that can ruin the careful planning....
But everything went fine, sky was exceptionally clear and everything was ready for a good attempt...
Although I've been in astrophotography for 3 years, I mainly worked with dslr and only recently bought myself an ASI 120 MC planetary camera, I had lots of doubts about my own skills, mainly about camera settings (choosing the right gain and exposure), plus to fine control an eq1 mount with an ASI on it is, well let me say not the easiest.....
This is the original footage, no changes or modifications made to it. I did only debayer it, because I record in FireCapture and it does better job if debayer function disabled during recording.
Exact capture time was 6:51am (25th January 2016)
Latitude of London,UK 51°
|Mind that for this photo I was tracking Saturn manually, not motors on eq1 mounts!!!|
It is all up to smartly processing the frames.
These are the saved screenshots for me to help finding a proper place near the airport of Gran Canaria, from calsky.com/cs.cgi and from heavens-above.com.

Update: for some reason my ASI cam missed one frame after the actual transit, no idea why. I was recording at average of 40fps, normal USB 2 port so might be the data transfer or whatever technical reason...
