27 Although the power is variable, each instrumen t under average skie s has a limit to the highest usef ul magnification. The gener al rule is that 60 power can be used for ever y inch of aperture. For example, the NexS tar 80 is 3.2” (80mm) in diam eter. Multiplying 3.2 by 60 gives a maximum useful magnifi cation of 1 92 power. Although this is[...]
