measured or sized?
Since any telescope, even a small one, can produce any given magnification with the right telescope eyepiece, magnification is not a useful way to rate a telescope. Therefore, the size of the lens or mirror (the heart of the telescope) is used as a general way to measure telescope potential. This is usually part of the telescopes model description. Question: Why is the size of the telescope lens or telescope mirror so important? Answer: The larger the telescope lens or telescope mirror, the fainter the objects a telescope will reveal (the more objects that will be visible), and the greater the telescope magnification it can use and still produce a good image. For example, at 120x, a ten inch telescope will reveal hundreds of objects not visible in a three inch telescope. In addition, at 120x, the 10″ inch telescope will produce images that are brighter and sharper than the 3″ inch telescope. Question: What is considered a large telescope or a small telescope? Answer: For amateur astron
