Would not you know it, Heavens Above's Web site was down for details, time etc, Found another page for ISS location, tho rough & waited approx 15 mins to make sure not to miss it.
Since my mount and gear is packed in car for dark sky tomoro, I had no option, but to use the ED100 F9 + Sigma 1.4x Tele on the Camera tripod, Pistal Grip, Kinda helped, tho when ISS was above say 50deg alt, found myself pulling the tripod over onto one leg and went with it
This one is about the best of a dozen during the pass !
