WebOct 29, 2007 · The f/ratio is of importance for extended objects, and particularly when faint. Image surface brightness scales as the inverse of the f/ratio squared. For example, f/4 image surface brightness is 4X higher than at f/8. This improves signal to camera noise, and shortens exposure times. For stars and brighter extended sources, a fast f/ratio is ...
