I read the wiki. I didn't see where it explained where the projector is and how it operates. Where is the mechanism located that projects an image of a celestial body on the atmoplane and how does it work?
A projection does not need a directional "projector". Consider a shadow puppet show in a cave by the light of a fire. The fire in the middle of the cave allows its occupants to project shadow puppets on the cave walls around them. The fire projects light, and is the "projector".
So what is the light source? The sun?
Then what is projecting the sun image on to the atmoplane?
Then take the moon projection. With your shadow puppet in a cave analogy, the Sun (which we don't know how it is projected) is the fire. Some sort of image of the Moon is the shadow puppet hands. And the shadow puppet hands/moon image is then cast on the cave wall/atmoplane.
- So where is the shadow puppet hands/moon image source located?
- And how does the projection create the moon wobble?
- And how does the projection create the solar flares?
- And depending upon where I'm standing on the plane, wouldn't these projected images look distorted in different ways. Much like if I'm way to the left in the front row of a movie theater as opposed to being in the middle of the back row?
The sun does not appear to change in size. Does FE address solar filter images/video as opposed to polarizing filter images/video?
Yes, solar filters are discussed on the Wiki page:

Q: Shouldn't a Solar Filter restore the sun to its actual state?
A: The principle behind a Solar Filter is the same as the principle behind a pair of sunglasses. It dims the scene for eye safety. The effect is a projection of light upon the atmolayer. Neither sunglasses or solar filters eliminate projections or reflections of light. Would wearing a pair of sunglasses eliminate the reflection of the sun off of the side of a car? Would a pair of sunglasses eliminate or shrink the projection on a movie screen inside of a movie theater?
Oops, sorry, I missed the Q & A at the end.
Yes, solar filters block a lot of light. Polarizing filters aren't just light blockers, per se. They work by diffusing light waves in specific directions, like horizontally and vertically. That's why when you rotate one you get a different effect.
There are basically two kinds of Solar Filters, White Light and Hydrogen alpha (Ha). The former blocks like 99% of the light so you can see the sun surface and Ha filters block everything except for the wavelength created by hydrogen atoms. So you can see flares and such.
Even from the Answer in the Q & A, I still don't see how it's addressing the fact that with a solar filter the sun does not observably change size. In your analogy if the projection of the sun on the side of a car and that car is 20 meters away and there's another car with the same projection 2 meters away, the projected image will be smaller on the far away car than on the close car. That's not what we observe with the celestial bodies. The projected celestial bodies should get smaller as they move away from us. They don't.
