I'm undertaking a project to build a 1.2/1.5m reflector. I've got a couple of old satellite dishes of the aforementioned diameters and plan to turn them into a pair of monster telescopes, starting with the smaller one and progressing to the larger based on how well the first one goes. Obviously, there are many steps to take and obstacles to overcome. After cleaning them up, the areas I'll need help on are:

-Finding a suitable material to coat them with for maximum reflectivity (biggest obstacle)
-Finding the focal point for light (the original receiver [in shot] is at the point to receive radio waves, but the point I've already calculated seems to be the focus of sound and is further out)
-Designing a focus system (probably just moving the eyepiece assembly back and forth)
-Installing a secondary mirror (in Schmit-Cassegrain orientation)

I'm planning on drilling a hole in the centre to insert an eyepiece holder. I've got all the mounting equipment for the back. A GoTo system would come later.

Any help is greatly appreciated.
