5.1 Sun
The Sun’s surface is alive with activity
so much so that astronomers often
desire to observe it.
However, using a standard telescope
would focus and direct too much
intense light into the retina, potentially
causing permanent damage (and…
possibly worse, no clear observations).
We can use pinhole to filter most light
then project over a distance to magnif
the surface for observations.
