This is my second attempt at an ISS shot. It certainly turned out better than the first:
Well, technically it may have been the third attempt because there were two passes this night and I botched up the first (tracked diligently but forgot to take pictures …).
I track manually while continually acquiring images and try to keep ahead of it in the finder, then let it drift over the chip area. One eye needs to stay glued to the finder while the ISS moves from near the horizon to almost overhead. It is probably the most sportive activity I engage in, as it requires to slowly shift from one yoga-like half-crouch position to the next for several minutes.
Currently ISS is trailed in its orbit by Albert Einstein, the automated transfer vehicle ATV4. It passed about 10 minutes later and I tried to take pictures of it, but as it is much smaller it remained an unimpressive dot.
