Mike,
At the time I did not have a telescope with solar filter, so I made this projection arrangement out of a pair of binoculars, a tripod and some card.
I should probably warn that this can generate quite a bit of heat in the binos, so I would not do it with anything really valuable or of large aperture, but if you have an old set of small aperture binos, it is a reasonable setup, especially if you want to show a group.
The whole thing worked well, and I got to show my kids who anyhow would have been too young at the time to look through a telescope properly.
-Ivan
