To look at the sun directly is dangerous and can make people blind.
The best solution to enjoy such an event is either to use solar glasses that are made for solar eclipses or to use a projection box put in the astronomical instrument as show the pictures in this page.
To make such a box is very easy: take a box of shoes and replace a side per a paper. Make a hole in the opposite side to be able to fix the ocular of your instrument, after fixer l'occulaire après having set-up your instrument, ready to clearly observe an object put in the infinite.
If you use another solution, let us know how you do!
