observing sunspots using a pinhole camera
... The resulting solar image was 24.1 centimeters in diameter. Noting several sunspots visible, I proceeded to trace their images onto the screen (This is much more difficult than it sounds since the Sun is a fast moving target, particularly at this projection size and no tracking involved. Several att ...

F-number
In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture) of an optical system is the ratio of the lens's focal length to the diameter of the entrance pupil. It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography. The number is commonly notated using a hooked f, i.e. f/N, where N is the f-number.
