Safe Viewing – Mirror projector |
Test out your system at 11a.m.on the day before the Eclipse. A number of people can watch together. The screen image can be traced around as a permanent record. The image is not sharply focussed but it is bright. | |
Cover a flat mirror with a piece of card with a 15mm diameter hole in it (note the hole does not have to be circular). Place it in sunlight. This is the projector. Reflect the image onto a shaded screen up to 10m away (under a tree, in a large box or an open room). | |
