You’ve been banned from YouTube?
No, I ended up deleting my account after some issues with missing posts, and no help at all from them. I first noticed the problem when trying to show a friend, at his house, my comments on a youtube video, but they were not there. After some head scratching , it turned out that I had to be logged in to youtube for them to show up, so any time I was not logged in to youtube, nobody could see them. Searching turned up that other people were having this problem, and youtube seems to have no intention of looking into it. So when I deleted my account because I didn't like their attitude, it also deleted all my previous posts I guess. The youtube comments seem to be dynamically loaded, it is not a 'flat' database, which means they can manipulate things in order to show different results to different people, opinion shaping perhaps. When I looked up the shareholders of youtube, it reads like a PTB glee club.
Was “garyinsooke” your username?
I couldn’t pull up anything at your link.
I used the Google site search " garyinsooke site:https:" then youtube.com, but this board wouldn't accept that. Just a garyinsooke search brings up my other posts (I'm not the same one asking decoration questions BTW), but nothing from youtube.
NONE repeat NONE of the imaging devices that photograph in space are any different in the way that they record light from digital sensors in cameras.
You have no idea what you are talking about. Look up the 'camera' specs, it's a spectral imager, and it's ISO must be in the millions. Do the stars in your image look anything like the ones from the ISS? Look at the CCD specs, it uses a lumogen coating to put UV into the working range of the CCD, so it goes from IR to UV. Which filters were in use when the image was taken, how long was the exposure? I'll let you look into that, I've had enough of your repeated questions. I've explained the vacuum stuff too, not doing it again. The Earth from Kagua is interesting, very blue though, will see if I can find details of the camera. When in Lunar orbit, the view always has the lunar rim in sight, same as pictures from the ISS, making me suspect it is the atmosphere making earth visible. It's possible the camera could have coated optics too, and that it is seeing UV, will let you know if I can find the specs.
Just saw your last post, so for you I will explain. Light created in the atmospheres of planets or moons WILL travel in the vacuum, we have all seen images taken with a camera on the Apollo missions of the Moon and Earth, from a distance, that can not be denied. But it is how far the light will travel, that is the question. The light created in the lunar atmosphere reflecting off the dark lunar surface is very weak, and will not reach Earth, the light from Mars will not reach Earth. The Moon is visible to us because the UV or EUV radiation produced in the lunar atmosphere, or Martian atmosphere, from solar radiation. It is not just visible light that is created, the UV WILL travel to Earth, and that UV/EUV will create visible light in Earths atmosphere, which we can then see. Vacuum UV will travel much greater distances because it carries more energy and has a self focusing tendency due to the nature of the vacuum itself, which is really a non-linear optical medium.
A problem encountered in using front illuminated (FI) CCDs is the lack of quantum efficiency (QE) in the UV region of the optical spectrum.This problem arises because the UV light is absorbed in the FI CCD electrode structure before it can contribute to the signal charge in the bulk of the CCD.
Is that you in Flickr?
More TOTAL and UTTER BS from YOU first you don't have to be logged into youtube for people to see your comments

Most of what we are told about the history of the Earth is bogus, conventional geology is a farce, and so is astronomy, and much of astrophysics. They really have no idea what the Sun is or how it works, as Dollard says.
I also believe the fear of nuclear radiation has been blown out of all proportion, and that we should have had cheap, clean energy long ago if it not been for the power of the oil, coal and gas industries to influence politicians. Yes, I'm an all around conspiracy theorist!

So now you call me an outright liar. Disagreeing with my interpretation of what can be seen in space is one thing, this is a science forum, but for calling me a liar, no more replies to you ever.
The main payload of the satellite would be a special scanner with a 20-degree angle of view, designated MSU-GS, capable of obtaining images in the visible and infrared ranges of the spectrum. From the height of its geostationary orbit, its angle of view would be enough to watch the entire disk of the Earth. Visible and infrared components of the imager were promised to have a resolution of one and four kilometers respectively and be capable of producing images every 30 minutes.
This pair of images represents the same viewpoint on Earth through two different sets of filters on the MESSENGER spacecraft. On top, three filters in red, green, and blue wavelengths were combined to make an image that approximates what the human eye would see. The green mass at the center is the Amazon jungle of South America. The deserts of West Africa are just visible on the edge of the Earth's disk below and to the right of South America. The bottom image is "pushed" into the near infrared; instead of red, green, and blue, it is composed of images taken through near-infrared, red, and green filters. Chlorophyll, the green pigment in plant leaves, is very strongly reflective at near infrared wavelengths, much more so than it is in red or green wavelengths, so the vegetated parts of Earth burst into bright red color.

- hard life here GaryN! Sorry for you, but what you try here is a complete none-sense! They are too full of scientific knowledge, to have time for rhetorical questions, alternative theories, ideas, or to see above top secret lies present everywhere around us! Really hard life!

If what we are told didn't work YOU would NOT be bashing a keyboard to talk to others around the world.
So what stops, say, Russian or Indian space enthusiasts launching one on a mini-satellite and pointing it into deep space?
...Originally developed for the Hubble and James Webb space telescopes, ...wavefront sensing
hard life here GaryN!
but I do know it is not as simple in space as it is within the atmosphere, that the light is of a different configuration.
