Shuttle launch lens determination
I have no idea if this will work, but I'm trying to use Google Maps to figure out what lens I should shoot the Shuttle launch with tomorrow night. Taking data from the awesome celestrack.com AGI Viewer Launch Scenario STS 128 launch I plotted where the shuttle should be when the main engines cut off. You can't see that point without scrolling, but it's where the lines the head off to the upper right are pointing.
Hopefully, we'll see how this all pans out tomorrow night.
