This series of videos looking at light, how it acts over distance, how and what we see in different levels of light.
Have made several interactive calculators with GeoGebra.

Experiment for you:
Your telescope will focus on an object 10m to 15m away, wait till dark, focus in on a dim object 10m to 15m away, (use a dim torch to illuminate if needed) , look with your eye, then through scope with a 10mm eyepiece. it will be a lot dimmer through scope. Not brighter.
Now, how can that telescope see stars or Neptune to dim to see with the naked eye, if its not making the light brighter?

There is only one possible conclusion. We have all been deceived, but many of us have awakened to the truth. Next up, you should all wonder WHY would they lie? There can only be one answer.
