Even the Keck Telescope in Hawaii uses trusses.

Absolute rubbish. If you a camera with automatic exposure with half the frame that is bright and half the frame that is dark it will set the shutter speed to be to fast to see faint stuff. The atmosphere is irrelevant. A camera doesn't know if there is gas in the atmosphere or not.

The problem is that the sky is black. Given that the sky is black, it would show the contrast of the star, however faint the light, because it's lighter than BLACK. If the sky was rendered gray or lighter you would be correct. There is no way for the camera to pick up BLACK but not lighter than black in the shot.

Thank goodness for that.
I'm not even sure that it's him, either.
He went from horndogging Zelda and Baby Metal to Starship Commander in the course of a few months.
Doesn't even talk the same, anymore.
...lol

That’s because there was a new Zelda game and a new BabyMetal tour happening.

Now there are moon landings happening.

No... If I went outside and took a quick automatic photo of the night sky you'd be lucky to get even the bright stars. To get very faint stars you need a camera that tracks the earth's rotation with exposure times going into several minutes. Even then you won't get the faintest objects. That's why photographs like the hubble deep field had extremely long exposure times.

Long exposures on earth are affected by the atmosphere by "seeing" which is a phenomena like the mirages you get from heat rising of a road in the distance... The atmosphere makes objects look like they shimmer and boil. You can use adaptive optics to reduce that effect and no atmosphere helps even more like for the Hubble telescope however it doesn't affect the principle of exposure times and how cameras work.

Yes it's all a matter of cameras and how they work with exposure and dynamic range. Go into a forest with bright light and dark areas and if you get the bright areas with the correct exposure the rest of the forest will be underexposed and dark.

Of course these numpties will never understand that.

And they have no intention of ever understanding it.

You're forgetting that the earth has an atmosphere that reflects light, even at night. If there was no atomsphere to reflect light it would not be an issue. I've taken night shots at altitude with clear skies and it's easy to get star shots.

What you retards are forgetting is that the atmosphere is the thing that reflects light and dims out the stars. If you can see the moon during the day here on earth WITH an atmosphere, you can see the stars on the moon during the day without an atmosphere when the sky is BLACK.

Yes but we aren't talking about during the day are we. On the moon during "the day" the sky looks black however the brightness of the moon in the shot affects exposure. On a movie each frame has a very short exposure time. Any hand held shots also have short exposure times or everything would blur just like any other photo.
