When you visit a new location like a planet, it's sky is as important to study as it's ground.

also the did they use the rover to travel long distances? was it actually important and crucial to the mission,cause thats an awful lotta weight to be carrying on a risky mission and the only thing that comes to my mind when I think about the rover is a short clip of it being driven like a toy,just for fun. just as a spectacle.
any one know enough about it to enlighten me?

A little link for you
www.photoanswers.co.uk...
From this link!
Do telephotos really compress perspective? It’s a common mistake to think that telephoto lenses compress perspective. The confusion is due to the face that most telephoto shots depict subjects a long way from the camera, and the change in perspective is due to the greater distance between you and the subject. So if you want to alter perspective, alter your viewpoint and choose a lens that fits the subject matter.
OK!
Yup, you're right. That's from Apollo 14. Apollo 11 and 12 didn't have that hold there, I see now.

Be honest with us all here.
Is that door from Apollo 11?
Like I posted before, it's all about angles. The moon is a half degree across. A 100 meter hill is half a degree high from about 11 km. A 10 meter tree is half a degree high from 1.100 km away. A 1.7 meter tall person is half a degree tall from about 200 meters away.

Interesting read..
But the subject in those pics is small, a person..
The other pic has no such small subject..It's a big hill...
BTW, I don't in anyway not believe the moon can look that big..
i've seen very big views of the moon from near the equator..
Why on Earth are you spamming this thread with that photo?
You expect me to answer a question about a photo that without any additional information
attached to it. Im sorry, but thats just baiting and not debating.
Crescent moon with earthshine setting behind Survey Point, near Mt Baker in northwest Washington State. Canon Digital Rebel, 300mm lens, ISO 100.

Now you show where it's impossible for them to raise their hands over their heads. They obviously could get their hands high enough to flip their sun visors up and down.
And what would have stopped them from using the edge of the door as a hold?
When crawling through the hatch, an astronaut would draw his arms in under his body, thus decreasing his width and allowing him to pass through the opening.

All those subjects photographed from the corresponding distance will appear about the same height as the moon, regardless of the focal length of the lens used.

Also did you note picture was taken using 300mm telephoto lens 6x magnification on the standard lens also as its a digital camera and the if the sensor size is not the same as a frame of 35mm film another magnification factor applies.
You can check this magnification factor on the Canon site

Because you've spent 25 pages doing everything you can to avoid having to explain this photo.

Very well, if you think it will help:
Crescent moon with earthshine setting behind Survey Point, near Mt Baker in northwest Washington State. Canon Digital Rebel, 300mm lens, ISO 100.
This link was provided with the original post.
Incidentally, this is neither spamming nor baiting. When you correctly answer why no stars are visible in the picture, the "why are there no stars in the lunar sky photos" will be settled.
