Prof. Lucie Green demonstrates how to make a safe eclipse viewer:
I wish I had my “Unusual Telescopes” book with me. Towards the back there is a photo showing two people each making a pinhole camera and projection screen using only their hands.
Perhaps people reading this may like to give it a try.
Hi Paul,
For fun I made one this morning.
I remember we used to try those kinds of crossed fingers tricks in the school playground when there was a partial solar. And in 2024 I took my small plastic colander to Texas.
Yesterday evening I set up my 10×50 binoculars (projection) and Astro Media solar projector to explain Wednesday’s event to my neighbours. The youngsters were fascinated with the cardboard box, its lens and mirrors.
Cheers,
Alex.
