Please note that getting banned on this channel is actually quite difficult. Ignorance and pseudo-science are fine. Personal attacks aren't. So farewell un4g1v3n1.

BTW, do you know if the video camera used in the first portion here was set on black and white?

[iafastro]

From the camera team in 1980:

"The planned space shuttle mission STS-4 will use the Skylab flight spare ten-color (near UV to near IR) photopolarimeter with boresighted 16 mm camera. The combined orbiter/instrument motion will result in a saw-tooth pattern of observations projected on the sky (between the 14 deg and 120 deg elevation limits) and will enable extensive measurements of the brightness, polarization and color of the background starlight to be made."

It will be included in my upcoming production....Thanks again for uploading...I've been watching your uploads for the past 5 hours straight....and much of what you have uploaded will be part of the huge project I had given up on. It's changed directions, and become a behemoth thanks to you!

Appreciate it!

You're welcome

@iafastro

called every other commenter a 'moron' or a 'troll' or some other choice word. i don't know if he had bad science within or not. sure yes, hurling abuses doesn't exactly get oneself friends. when i tried getting him to provide evidence for star fotografi in space during 'sun' time, he promptly blocked me! i returned his favor by challenging him to prove his point. and of course, blocking him as well.

@un4g1v3n1

Aww sorry...did I hurt your feelings?

[TheHeather1985]

@un4g1v3n1 I told you I'll only make comments when it is full of pseudo scientific garbage. Your earlier argument was flawed and I pointed it out. You just respond with personal attacks. I can't in good conscience let people like you and nephilimfree go around making scientific illiterates of everyone.

@un4g1v3n1 "Pictures of stars in space is as easy as adjusting settings...PERIOD."

That rebuttal makes no sense. When we took pictures on the Lunar surface the reflected light drown out the light of the stars. In the above video this is light being reflected from the moon and hence must be dimmer than the light on the lunar surface. This means you cannot claim just because stars are present in this video they should be present in lunar surface photos. Your argument is flawed.

[un4g1v3n1]

For those of you who are intelligent, and have basic logic when using your brains, unlike the troll that followed me here. He's a stalker troll...You ever get one of those? Well, anyhow, if you will listen to the speaker of the video, and compare what he says, and the video of the Earth/Stars/Atmosphere, to past missions from NASA, especially Merc 7, and the Apollo missions, you'll begin to clear the tang from your eyes and mind, and awaken to the Apollo Fairy Tales! Peace!

[un4g1v3n1]

@TheHeather1985 It's not a critique, it's moronic. Pictures of stars in space is as easy as adjusting settings...PERIOD. Any moron who has the intellectual level of say, half of you, and the ability to explore the settings for different effects can see that you are full of crap. Another troll trying to sound smart and failing miserably. I'm definitely concerned that continued conversation with you will inhibit basic brain functions, so go ahead and find a new billy goat!

[TheHeather1985]

@un4g1v3n1 Oh I see where the confusion was. I was referring to the pictures being taken on the lunar surface. Do see my above argument. It will explain why we can see the stars in the video above but why this would not imply that we would see stars from pictures taken on the lunar surface.

[TheHeather1985]

*correction* the photos taken FROM the moon. Just to reiterate the light from the atmosphere MUST be of lower intensity since there can't be more light from a reflecting surface than from the original source. I look forward to your response to this critique.

[TheHeather1985]

@un4g1v3n1 While the reflection coefficient of the Earth's atmosphere may be higher than that of the surface of the moon this isn't the only factor in determining whether or not light pollution will drown out the stars. Since this is the Earth's atmosphere being lit by the light reflected by the moon, it follows that the intensity of the light in this video will be considerably less than the light in the photos taken by the moon.  Your argument is flawed.
