  1. As an amateur astronomer of 30+ years, Ive built my own telescopes and ground precision optics to a surface accuracy of ⅛ wave of light and hand corrected them to a perfect parabolic curve... by rubbing two pieces of glass together with progressively smaller grit. I can tell you its virtually impossible for anyone living in a desert to figure out how to do that.
