The largest man-made object in space that I have imaged is the International Space Station (ISS). About the size of the Eiffel tower it also flies in an orbit at a height of just over 400km. Culminating usually at lower altitudes than the zenith brings the imaging distance close to the distance from InFINNity Deck to the Eiffel-tower. The ISS is about 109m wide, which is as wide as the Eiffel-tower's base.

On 30 March I tried to image ISS for the second time using the same equipment as the day before, but this time using a 4x Powermate, making the Celestron C11 XLT EdgeHD f/40 (focal length 11,176mm). The distance between InFINNity Deck and ISS was about 580km at this recording.

ISS as imaged @f/20 on 29 March 2021.

On 29 March 2021 I gave it my first attempt using the Celestron C11 XLT EdgeHD, 2x PowerMate (so f/20) and ZWO ASI174MM camera. Tracking was done by programming the orbital parameters in the mount, after which the mount automatically tracks the space station in two axis.

If you have any questions and/or remarks please let me know.
