Pinhole projectors
These are a safe, indirect viewing technique for observing an image
of the Sun. While popular for viewing solar eclipses, pinhole projectors suffer from the same
shortcomings as unmagnifi ed views when Venus approaches the edges of the Sun. Small features
like the halo around Venus will not likely be discernible. Pinhole projectors and mirror projection
techniques are at
