I've just spent a very enjoyable two evenings watching the ISS pass across Sydney skies, and there is the prospect of another two passes in the next two days (if the weather gods permit).
The first pass (2nd July) I put the Heavens-Above orbital data into my LX90, but it did not track the ISS at all. It thought its orbit was fifty degrees behind where it was. I found out that the orbital data must be gleaned from HA on the day (and preferably within a couple of hours of the pass).
When I repeated the effort tonight, the LX90 tracked quite well - but not well enough to put it consistently in the field of view of a 1/3" prime focus video camera. To get the ISS in the FOV, the LX90 needed constant nudging via the finderscope.
I hope to repeat the effort tomorrow and Sunday. The pass on Saturday is (according to HA) mag -3.1, max altitude 50 degrees (over Sydney) and should last for over 5.5 minutes.
Regards,
Tony Barry
