This composite illustrate the reason why some Sun eclipses are annular : even if the Sun's and Moon's diameter seem to be equal (about 1/2 degree), it's not exactly the same. The Sun and the Moon are more or less big, depending on their distance from the Earth. Often, the Moon is bigger than the Sun: a total solar eclipse occurs. Sometimes, the Sun is bigger dans an annular eclipse occurs.
Remember that those kinds of eclipse occur when the Moon is New, so almost invisible. Conveniently, I choose to take a picture of the Moon (24 hours before the Full Moon) and the Sun on the same day.
Let's note that I speak about apparent diameter, i.e. the diameter of thoses objects in the sky.
