2023年9月9日 · The aperture of a telescope is the size of the primary lens or mirror. The larger the lens, the more light it can capture which results in higher quality images and the possibility to capture objects that are farther away.
Aperture: The Importance of Aperture Size in Telescopes
When it comes to choosing a telescope, one of the most crucial factors to consider is the aperture size. The aperture, often referred to as the "light-gathering power," plays a significant role in the performance of a telescope.
What Is a Good Aperture for a Telescope?
Aperture refers to the diameter of the lens or mirror in a telescope. The aperture is essentially the telescope’s “eye,” and it plays a crucial role in determining its capabilities. The larger the aperture, the more light the telescope can gather, which leads to more precise, sharper images.

Telescopes 101: How Big A Scope Do I Need? What You Need
Many deep space objects are very large, but very faint. To see them, you need to make their images brighter, not bigger. The larger the telescope aperture, the brighter the image at any given power - plus, it's easier to see detail in a bright image than it is in a dim one.
Telescope aperture: How Much Do You Need and How Much Can …
To generalize, a mirror based telescope needs to have about 1/3 more clear aperture than an APO refractor to deliver comparable visual performance. That figure correlates well with my personal experience, as I find the overall performance of my 4.5" Stellarvue refractor about equal to a good 6" SCT or Newtonian and Gordon's 6" Stellarvue about ...

F-Numbers and F-Stops Explained: Mastering Focal Ratios for …
6 天之前 · To calculate focal ratio, divide an optic's focal length by its aperture. For example, a Celestron 8" Schmidt-Cassegrain telescope has an aperture of 8 inches and a focal length of 80 inches. Dividing the focal length by the aperture gives an f-number of f/10. Focal ratio affects telescopes and cameras differently.
List of largest optical reflecting telescopes - Wikipedia
This list of the largest optical reflecting telescopes with objective diameters of 3.0 metres (120 in) or greater is sorted by aperture, which is a measure of the light-gathering power and resolution of a reflecting telescope.The mirrors themselves can be larger than the aperture, and some telescopes may use aperture synthesis through interferometry. ...
