Oh Matt and Ric, what more could you want? I have given it to you all on a plate.
You'll find that the focal length of the ABC tower in Brisbane was calculated to take a square shaped lens on a trapdoor cover at the apex of the tower. I did the calculation over 20 years ago. The height of the tower is the correct focal length for a lens at the apex which is the size of the trap door. In fact, all you have to do is make a lens roughly 1 metre X 1 metre square, and you will have the largest refractor ever built in the world.
Conversely, you can place a mirror of a dimension equal to the four lower posts, and it will create one of the largest stationary Newtonian mirrors in the world.
It will give you images equal or better than those produced through the Hubble Telescope.
I guess to understand why NASA built the Hubble Telescope given this simple solution, we would have to look at the cost of house mortgages. That's right! The boys at NASA just wanted to make quid. They needed to pay off their mortgages.
Psst! Can you keep it all to yourselves. I just want to hear someone else say it purely through an act of reason as opposed to pollyanna.
