Observing location
250mm SCT
ZWO ASI 290 mm
Baader IR pass

This is the first time I have used the ZWO camera for imaging the ISS. The big advantage compared to my previous camera seems to be its greater dynamic range which allows the panels and cooling radiators to both be reasonably well exposed. The exposure time of 5ms was possibly a bit too long, next time I might shorten that and up the gain. The telescope tends to vibrate during tracking and shorter exposure would help to freeze that motion. 

This was a lucky observation the clouds disappeared only 10 minutes before the pass.
