I wonder if any of the conspiracy theorists who complain about the lack of stars in apolo photos have ever tried to take pictures with stars in on earth? If so they might find that trying to get a person to stand still long enough to avoid bluring.

I used to do some basig astrophotography at Uni, and with fast film (800 asa minimum) a 10 second exposure would result in approximatly the same results as the nakid eye would be able to see in a dark location.

Of course they haven't. That would require intelligence.

Were you ever able to get any good results with planetary photography? I've read that with film it's very hard to do.

It would also require knowledge of how to use a camera, which apparently is something else a lot of conspiracy theorists (all "expert photographic interpreters") don't seem to have.

Yesterday I acquired a copy of The NASA Mission Reports: Apollo 11, Volume Three. In it, the editor, Robert Godwin, has this to say:

Quote:
The still-image camera employed by Aldrin and Armstrong was using a very narrow aperture (f/stop) combined with short shutter speeds due to the intensely bright lunar terrain. This is well documented here and explains to anyone but a total idiot why there are no stars apparent in any of the lunar photographs. (For anyone who still can't figure it out - try taking any camera outside on a clear night with ordinary color film in it and then shut down the aperture to f-22 and expose the frame at 1/250th of a second. I guarantee that you won't see stars in the resulting picture.)

For the sake of any reader that might read this in some hazy distant future. Yes, there actually was a time at the beginning of the 21st century when many people believed that the Apollo moon landings were filmed on a Hollywood back-lot. Their research can be found alongside the findings of the flat-Earth society and the many cult cliques who insist that the world actually ended in 1999 ... I digress...
