Does the diameter of a telescope control its magnification?
No, you can change the magnification of the telescope by simply changing the eyepiece. The two most important powers of the telescope, light-gathering power and resolving power, depend on the diameter of the telescope, but it does not control the magnification.
What are the 4 properties of a telescope?
I know of at least three. I hope these help: - magnifying power - light gathering power - field of view
How much greater is the light-collecting area of one of the 10-meter Keck telescopes than that of the 5-meter Hale telescope?
A 1 m telescope has a collecting area of pi x 1 x 1 = 1 piA 3 m telescope has a collecting area of pi x 3 x 3 = 9 pi.Therefore, the bigger telescope collects 9 times as much light.
What does the light gathering ability of a telescope depend on?
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
A telescope that suffers from chromatic aberration and has a low light gathering power is most likely?
a. a small diameter reflecting telescope.

Why does the light gathering power of a telescope vary?
The light gathering power of a telescope is directly proportional to the area of the objective lens of the telescope.
How many times bigger does the image appear in a refracting telescope?
That will depend on your telescope power.

The light gathering power of a telescope increases as the objective increases?
Yes, light gathering power is proportional to the area of the objective. The more light a telescope can gather, the better the telescope will be able to allow the user to see.

a. a small diameter reflecting telescope.
What power of an optical telescope is most affected by light pollution?
A small aperture.
What is the ratio of the light gathering power of a 1.39 m telescope to that of a 0.79 m telescope?
(1.39/0.79)2 = about 3.1 (rounded)
How do astronomers use active optics to improve telescope resolution?
In past years, the light collecting power of telescope has been improved by building telescopes with of larger diameters with larger collecting areas, thus allowing for the detection of fainter and more distant objects
How far out can a hubble telescope see?
The Hubble telescope with the light-collecting power of the W. M. Keck Telescopes can see 13 billion light years away based on the furthest detected galaxy to date. In comparison looking up into the sky on a very clear night, the Triangulum Galaxy can sometimes be seen by the naked eye. This is a distance of 3.14 million light years. The Andromeda Galaxy is also sometimes visible. This is a distance of 2.5 million light years.
