I took some measurements and was drawing this up when it occurred to me that the easiest way to make this is to have it 3-D printed out of clear or translucent plastic. That will save you from having to scrounge up the plastic & glue the pieces together. So I created the model on CAD and uploaded it to Shapeways and it would cost them $7.50 to print it up plus probably a few more to ship it. That’s probably about as much as if you went out & bought the plastic yourself. What you would have to do is trim it with a file (if it needs it) & paint it with model paint. Then you glue it onto the sextant with 5 min epoxy & add the Velcro patch for the little Photon LED light.
Does that sound like it might work? Here are the shots of the 3-D model. The black areas you paint first with white paint to make it reflective on the inside, then black paint on the outside. The red areas you keep unpainted
