Sorry for tracking you down online but what kind of telescope do you
have here?

That's just a cheap hand-held thing that happens to project the sun
well without melting anything inside itself. It was a great way to
follow the Venus transit, but fairly useless for anything else
astronomical. I wouldn't try doing that with anything expensive due to
the possibility of damaging something by heating it inside. I used
that setup to show the event to some of the children at our local
school.
