Then there's the simple fact that wavefront sensors are simply devices for measuring the aberrations of an optical wavefront.
Cassini exposures can be much shorter than you specified. I've seen stated exposures of less than a second, for images taken through red, green, or blue filters (i.e. no infrared or UV was allowed through).
SERIOUSLY you don't have a clue!!!!

The reason they don't use camera like optics as you put it is weve gone digital but i assure you had they put a camera visible light doesn't suddenly change frequencies. So if the visible spectrum is missing where did it go? .

Wide Angle Camera [WAC](20 cm f/3.5 refractor; 380-1100 nm; 18 filters; 3.5ox3.5o)
Narrow Angle Camera [NAC](2 m f/10.5 reflector; 200-1100 nm; 24 filters; 0.35ox0.35o)

you have one star it is spinning and planets are orbiting around that star at such and such speeds ,
for earth around 60k per hour . Now earth orbits the sun at this speed because the sun exerts a certain amount of gravitational pull on it . And the earth pulls away at a cirtian speed as well because of a little thing called cintrifical force , So wile the sun is pulling earth towards it the speed and mass of earth are pulling away from it.
over the coarse of millions of years a balance is reached were the suns pull and the earths pull equal out .
the result is our orbit . Now in order for the sun and earth to reach a balance each has a cirtian amount of MASS .
with the KNOWN factors of earths speed and earths mass you can calculate the suns mass .
Now if the sun was hollow as you think it would have to be MUCH larger in order to exert the same amount of force on earth as the mass HAS to be there in order for earth to be were it is,
The suns size is correct for the earths size and mass to be in the orbit it is.
Look up the suns MASS we know within a very small amount exactly what it is > you don't need to send a probe into it to learn this any more then you need a measuring tape to tell how far the moon of any other body is.
The suns mass and size equal what we look at each day and wile it does expand and contract slightly tahts because it gets hotter and cooler at times.
But hey dont take my word for it just take science class and stay AWAKE this time.
so If the sun had less mass earth would pull away if was larger ((in order to be hollow earth would be toast
So if the visible spectrum is missing where did it go?
Oh and the Moon that cant be photographed in space
One of the Expedition 32 crew members aboard the Earth-orbiting International Space Station captured this image of the full moon on Aug. 1, 2012. Other pictures in this series depict a totally different image of Earth's natural satellite because of distortion caused by the atmosphere.
Hmmm ...
I have a question - What if 'hollow Earth' theory is correct? Would a hollow Earth pull away from a hollow sun, or orbit it?

it is not easy at first sighting to recognize the heavenly body as the full moon. Another picture in this series depicts a totally different image of Earth's natural satellite because of the lack of distortion caused by the atmosphere.
The ISS consists of two framing cameras. The narrow angle camera is a reflecting telescope with a focal length of 2000 mm and a field of view of 0.35 degrees. The wide angle camera is a refractor with a focal length of 200 mm and a field of view of 3.5 degrees
Other pictures which means that picture was NOT distorted by the atmosphere.

It didn't go anywhere, the simple optics are just not able to 'focus' the wavefront, it is not a 'photon' of the type that simple optics, such as our eye or regular camera can 'decode'. Again, a simple experiment can prove it one way or another and end all the speculation.

From that site:

If you look at the other images of the Moon in that set you will realise it is taken through Earths atmosphere. The field of view from the Cupola does not allow for seeing into deep space, only space around the edge of the Earth. There are no back windows to see deep space from, that's why a photo would have to be taken while on an EVA, or by using the Canadarm2 which can point out into deep space. You sure must drink NASA Kool-Aid by the gallon. What NASA shows us is not the important issue here, it is what they DON'T show us, the stuff that is so simple that everyone overlooks it. Proof, I want proof, scientific proof.
And don't keep going on about CCDs, they are a only part of the system, you need the complex optics and the software too. Does your camera have those?

Well, under a different model, the Sun would be an electromagnetic machine, and gravity would be a magnetic phenomena. If the Moon (and probably all the planets too) are hollow, then you are looking at a different mechanism for the orbits of planets and moons. Maxwell stuff, but coincidentally, if you use Maxwell equations they turn out the same as gravity base calculations for orbits etc. Which is it? I'd go with gravity being a magnetic phenomena.

The denser the atmosphere they are looking through, the more the image of the Moon is affected. As the Moon moves further away from the Earths rim, it is less affected. In the 'sweet spot' it will look just like the Moon we see from Earth.
