I shot this from up on a hill in Fremont with my old Canon G15. This is a stacked image of four 6-second exposures. In my previous post I messed up the distance: it is actually ~335km away from the launch site according to Google Maps.
I know my stuff isn't professional, but it is so much fun and I highly recommend "rocket hunting" to anyone who can!
Thanks!! Yep, lots of planes flying around, going to San Francisco and San Jose!
