ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************
It isn't a heliostat, but we've just purchased a solar telescope from John
Welsh at Scopin' USA
http://www.scopinusa.com/
He's developed it himself, and there's no way for anyone to hurt their eyes
using it to look at the Sun; the Sun is projected inside of the telescope
onto a screen that's several inches across and can be viewed by a small
group together. Sunspots can be measured, and the image can be traced on
light paper. Very affordable, and fairly new (he hasn't started
mass-production yet.) Great for a small portable program. (The only way
you could hurt someone is by picking up the telescope and swinging it at
them.)
