slighty off topic but still on topic if that makes sense,

Is resolution and light grasp determined by clear aperture surface area or just the bigger is better rule?

if say a 8inch newt has a 1 1/4inch secondary does that mean it's a much closer comparison in both light gathering power and resolution? to a 6inch apo that is....
