A telescope has two general properties: how well it can collect the light how much it can magnify the image A telescope's ability to collect light is directly related to the diameter of the lens or mirror -- the aperture -- that is used to gather light. Generally, the larger th...

To achieve the best results, select a telescope with a large aperture and high magnification to gather more light and reveal finer details. Some popular subjects include the planet Saturn and the surface of the moon. Attach your camera to the telescope using a camera adapter for precise imagin...
does not absorb light or interact with it. So that literally makes it invisible." If this is not strange enough: since 1998 we know that the expansion of the universe is accelerating. To explain this an even more mysterious ingredient is needed: 'dark energy," a term that simply ...
How does a telescope work? So in very simple words, a telescope is a bit of a bucket of light, bucket of photons. So using a lens or a mirror that is inside this tube, you collect the photons, the light, from an object and concentrate it. Focus it in a specific point so that ...
It may surprise you to hear that a camera lens is the best way to capture the Milky Way, not a telescope. The high magnification focal lengths of a telescope are great for zooming in on deep-sky objects, but to reveal the beautiful structure of the Milky Way, you need to shoot wide....
A light microscope works very much like a refracting telescope, but with some minor differences. Let's briefly review how a telescope works. A telescope must gather large amounts of light from a dim, distant object; therefore, it needs a large objective lens to gather as much light as pos...
The glass lenses in a telescope refract (bend) light rays from distant objects so they seem to be much nearer. But in a lighthouse, the Fresnel lens wrapped around the lamp concentrates the light rays into a powerful and parallel beam so people can see it, with just a naked eye, as ...
