The second video in this series explores how to understand the magnitude scale, starting with visible stars in the naked eye range, going up in brightness to understand the relative brightness of bright planets such as Venus and Jupiter and then the full Moon and Sun, and then heading back down the magnitude scale (but UP in numbers – all explained!) to dimmer objects.  In addition to visual magnitude, absolute magnitude, integrated magnitude and surface brightness are covered.
