Hello,
NASA kindly e-mailed us to notify of an ISS passage over our back garden so I decided to “have a go” with the Tak Mewlon 180 F12 and ASI 120MM CCD camera at prime focus (2160mm).
I used a heavy duty photo tripod and a binocular alt-az fork mount and tried to follow the ISS in the finder scope. The ASI 120MM ccd is 1280x960 pixels fiving a FOV of approx. 6x4 arcmin, so I wasn’t expecting great results. From the 8126 frame AVI (over 9 GB) I manually found a handful of frames with the ISS in the FOV, the remaining 8100 were empty!
Here are two of the better frames; no stacking was possible so these are just single frames.

Cheers
