I focused and set the exposure on Venus, which was predicted
to be approximately the same size and magnitude as the ISS.
The mount would not automatically track the ISS, so I
disengaged the drive motors and used the finder to manually
align the telescope during the pass. This was the first time I
have tried to image the ISS, and it was difficult. The ISS
appeared in some fashion in 122 of the 10, 928 frames. I picked
two near the zenith, and applied levels and curves in Photoshop
CS5.
