First International Space Station close-up imaging since the Crew Dragon mission. Timing is perfect, the weather was so bad in the past few weeks and it just got back to clear days when high elevation flybys began. This was the very first bright pass with the maximum elevation of 53°.

I was experimenting with camera settings, lowered the expo value and pushed gain value up a bit. I wanted to see if I can lower the exposure time to avoid any blur effect. But I had to realise that my camera has some limitations I was not aware before (thanks for Philip Smith and Martin Lewis for this valuable information). What I mean is the 224MC camera has rolling shutter instead of having global shutter. Basically using a camera with rolling shutter for this purpose will always have some level of blur effect on the frames. This video is about the difference between rolling and global shutter.

Here is a screenshot of my camera settings.

And finally a wide angle time lapse video of the flyby.
