Hi,

Good post first off. :D

My husband and I will be having family vacation with our two small children at the beginning of July. At the front of the trip we will be watching the final Space Shuttle Launch out of Florida. From the information we know now is that we will be at a distance of at least 15 miles.

Like you metion in your post, the common question....what should I look for when binocular hunting for this one event? For me and our small kids (5 & 7)? Any suggestions? We are okay with it if we can't read any of the astronauts patches on their suits...lol, but realistically we'd like to be able to see the shuttle 'fire' and smoke building up before and after launch. Any suggestions?

wondering if you can help me :)

I have a video camera with 14x optical zoom. If I know the size of an object, and I am at full zoom and the object fills the frame, can I calculate my distance from that object?
