The projection method is a safe and effective way to observe the Sun, its surface features, and solar eclipses. By projecting the Sun’s image onto a flat surface like a white piece of paper or a screen through a pinhole, you can view details like sunspots and the progression of a solar eclipse—without ever looking directly at the Sun, which can cause serious eye damage. Projecting the image of the Sun onto a screen using a simple mirror can also be used to calculate the diameter of the Sun!
Several factors affect the quality and accuracy of the image obtained through the projection method such as the distance between the image and the mirror, the size of the slit and even the reflective area of the mirror. Adjusting these parameters can result in a much better and accurate image for calculations.
This method has been used for centuries by astronomers to observe solar phenomena without damaging their eyes. It’s perfect for classrooms, solar viewing events, or casual observation. Never directly look at the Sun through binoculars or a telescope unless you have proper solar filters, as this can cause severe eye damage.
