Huygens Question - Using a Pinhole Box in the Giant Pinhole Irvine

[hutchphd]

What are we trying to do here, split hairs and score points off each other or correct fundamental misconceptions?

I can only speak to what I am trying to do: no points, imagined or otherwise, are involved. What you do is up to you. Please do not presume to speak for me.
The concept of a giant camera obscura has much pedagogical merit. I am interested because the diffraction scale is fixed by the wavelength of the light so that the diffraction limited angular acuity of a large camera scales with size. That pedagogy was being totally lost on the OP.
