I am researching cheapest easiest way to build my tele. But I want it most compact and maksutov is a idea. I want to use no glass traditional lens but MURA , Photon Sieve or Fresnel. I stucked in one idea. As you know , maksutov have 2 lenses , one big and opposite small one. ıf I want to build this , do i need to print a photon sieve on to a flat mirror ? How would it be made work ?

Thank you ,
