Observed ISS-Shuttle solar transit at approx 100x with PST Ha at about 2km east of the centerline.   These solar crossing observations are inherently videographic.  Did it visually anyway for the practice.  The effect was subtle with the ISS-Shuttle crossing the disk 1/4 to 1/2 second.  Target had an angular appearance (size CalSky computed at 24 arcsec) but was more of a solar light diffraction effect around the edges of the object than a dark object through the HA lens.  The square ISS solar panels could be made out as different from the ISS body.  Took some time to chart out the crossing event to assure the observed object cooresponded in size, speed, time and angle of travel to the predicted ISS path.  Clear Skies - Kurt
