Have to say the last shot of the boy in the air ... I am so upset those two girls were in the way!!!
And you didnt get their phone numbers?
As Alien8 has shown it should be easily possible to sort out the problems. Sometimes you just take a photo and then find somethings there that you wish wasnt. Still a great action shot.
First picture you can cheat, take two photos, one with the camera focused on the horizon, the second with it focused on the telescope, combine the background from the first with the telescope from the second and it would be a totally different shot. That would give the whole picture in focus, except you mightnt have wanted that effect.
