How much smaller or larger times angular resolution does a 12 inch diameter telescope have?
than a 4 inch diameter telescope
Using Dawes' formula, theoretical resolution in arcseconds = 4.56/(objective diameter in inches), so resolution improves directly with increasing aperture. For a 4-inch scope, the resolution is 1.14 arcseconds; for a 12-inch, it's 0.38, three times better.
In real life, this only holds true for unobstructed telescopes (refractors and a few exotic reflecting designs) under perfect atmospheric conditions. For obstructed telescopes, a rough rule is to subtract the diameter of the central obstruction from the objective diameter to determine the resolution limit. In addition, atmospheric turbulence generally affects large telescopic apertures more than smaller ones, further reducing the larger scope's advantage.
