Department stores and camera shops which do not know anything about telescopes, loudly proclaim their telescope's magnifying power. Magnification is the least important power of a telescope. Amateur and professional astronomers know that the light-gathering power and resolving power are the most important.

Light-gathering power is proportional to the area of the telescope objective. A lens or mirror with a large area gathers a large amount of light. ... That is, the ratio of the light-gathering power (LGP) of the two telescopes A and B is equal to the ratio of their diameters squared:

These are the measure of its efficiency. All three are related to some extent, ... Light-gathering power of a telescope mainly depends on its aperture diameter. However, it is the system ... Aperture directly determines how much of the light from distant objects is captured. Therefore, light-gathering gain of a telescope vs.

Next: Resolving Power of a Telescope; ... Light Gathering Power (Page 101) (Problem 5-1); ... The larger the diameter of a telescope mirror, the more light it collects. Similarly, the larger the mirror, the less time it takes it to collect a given amount of light. This second relation can be expressed as:

The light-gathering power of an optical telescope is directly related to the Diameter of the objective lens or mirror. Note that the area of a circle is proportional to the square of the radius. A telescope with a lens which has a diameter three times that of another will have nine times the light-gathering power.
