Another attempt.  This is using a 23A filter rather than the 642nm bandpass filter.  Luminous transmittance ~30% rather than ~10% so shorter exposures but more atmospheric turbulence.  ISS was about 520km away when I took this, more images acquired so my manual tracking has improved.  This is most definitely not astronomy but still an interesting technical challenge.
