I've seen the ISS multiple times and a few comets and assorted satellites. It's strange how my love of astronomy from when I was 10 (and had a south-facing window) basically went to sleep for 30 years until I picked up a sextant and went "huh...I bet this would be useful sailing..."
Thanks for the link. I used Google Earth to refine my house lat/lon. so I could see Iridium flashes out the back window.
