1 horse sized duck, or 100 duck sized horses?

Common question. I should probably make this a sticky.
The answer is; it depends on your light pollution, but the rule of thumb is 110 duck sized horses, reduced by approx. 12 duck sized horses for each Bortle class of light pollution you're experiencing. Only go for single horse sized duck if imaging from excellent dark skies (e.g. class 1 which is approximately 1 horse sized duck). The granularity of the smaller horses allows you to fine tune.
