thats awesome,, so nasa spots some black spots that could be anomolies or just photoshoped showing nothing but black spots on some land and we are supposed to take that as being "proof" but then we have people including a president that has seen ufo's in person, we have odd shapes and faces and "naturally" occuring right angled objects on mars that are "nothing" and even photos that show cut and paste jobs from nasa of mars,, but oh look we have black spots on the moon,, theres proof!! lol give me a break

Well, actually, no. The cameras used on the Apollo flights were specially made
Hasselblads.

There are quite a lot of photographers out there that will tell you that even though the camera, and lenses and film designs are 35 years old, they are probably superior to 98% of the commercially available equipment currently on the market. The most advanced digital equipment out there today has only approached this level of quality in the past few years or so.

BTW, these were film cameras, so your use of the term “pixel” is incorrect.

The reason that stars do not show up on the photographs has to do with the dynamic range of the film emulsion.

genesiss, is English your second language?

If you read the above Hasselblad link, you will see that the camera and film magazines were silver coated to minimize the amount of thermal variation from the incoming solar radiation.

Are you familiar with vacuum bottles (or Thermoses)? Do you know how they keep coffee hot or ice tea cold for so long? There are two main mechanism at work there. One is that the inner flask is surrounded by a vacuum. This eliminates the effect of air in the transfer of heat via convection. The other is that the inside of the bottle is silver. This reduces the loss of heat through radiation.

Since, as I am sure you are already aware of, there is no air on the moon, the transfer of heat to the camera film via convection is not an issue. The reflective exterior coating takes care of the thermal radiation issue. That leaves conduction as the primary source of heat. Since the cameras were obviously carefully handled and stored throughout the mission, it would have been relatively easy to avoid putting the camera down on top of a hot surface.

Oh, and perhaps you can explain just how NASA “photoshopped” the moon pictures in 1969?

Ah, the Van Allen Belts. Here is a pretty good synopsis of the Van Allen Belt issue.

Please read through that and let me know exactly which part of his analysis of the problem that you disagree with. If his data is flawed, please provide a link to data that you consider to be more accurate. If his calculations are wrong, please provide the corrections.

While you are at it, please provide a specific example of where BadAstronomy.com is wrong.
