As I had no Telrad yet on this configuration, locating precisely the ISS going up in the sky was not easy at all as at start the ISS is not bright !

I had to start in manual movie mode ISO 6400 exp 1/30 sec (then I was able to see a bright star) and about 300 mm focal length.

When I catched the ISS and the tracking was Ok, I had to change quickly to ISO 800, exp 1/1250 sec and zoom to max 3000 MM (blocked on f/8).

When tracking was not as precise as expected I had to play on zoom for a few seconds and act on the knobs of the finder Taka refractor.
