Thanks for the article, Mike.
In your composite pic, one person appears to be using a telescope to project a large image of the sun onto a screen. I had this idea, too, though as soon as I waved a bit of A4 in front of the eyepiece, the paper caught on fire.
Easy to see that any slip-up using filters etc. could result in instant blindness
Placing a camera near the eyepiece could instantly wreck the camera, surely?
Projecting an image onto a screen then photographing the screen sounds safe. But how to do it?
Cheers
