When you enter any new field of science, you almost always find yourself with a startling new language of technical terms to learn before conversing with the experts. This is certainly true in astronomy both in terms of terms that refer to the universe and terms that describe instruments of trade, the most prevalent being the telescope. So to get us off first base, let's define some key terms that relate to binoculars so that you can talk to them more intelligently.
The first area of expertise in telescopes is related to the types of telescopes people use. The three telescope designs that most people use are the refractor, the reflector, and the Schmidt Cassegrain telescope.
* Refractor telescope uses a convex lens to focus the light to the eyepiece.
* Reflecting binoculars have a concave lens which means it is bent inward. It uses mirrors to focus the image you eventually see.
* The Schmidt Cassegrain Telescope uses an incorporated system of mirrors to capture the image you want to see.
* A binoculars telescope uses a set of mounted and synchronized binoculars so that your view of the sky is 3-D.
Beyond the basic types, other terms refer to the parts of a telescope or the science behind how the telescope works.
* Collimation is a term for how well a telescope is tuned to give a nice clear image of what you are seeing. You want your telescope to have a good collimation so that you don't get a false image of the celestial body.
*Aperture is a fancy term for how big the lens of your telescope is. But it is an important term because the aperture of the lens is the key to your telescope being powerful. Magnification has nothing to do with it, it's all in the aperture.
* The focuser is the housing that holds the telescope's eyepiece, or the one you'll see, in place. The focuser must be stable and in good repair to have an image you can trust.
* Mount and tack. Both of these terms refer to the tripod on which your telescope sits. The mount is the actual tripod and the wedge is the device that lets you attach the binoculars to the mount. There are mounts and wedges to aid you in a better viewing session and keep your expensive telescope safe from falls.
* An altazimuth mount refers to the tripod of the telescope that holds the device in place and makes it useful during star gauging sessions. The ultazimuth mouth allows the binoculars to be moved both horizontally (which is the azimuth) and vertically. That way you have the full range to see things close to the horizon or directly above.
* The meaning of coma differs from the meaning we're used to, and that's a good thing. A coma is a blurred area at the outer edges of your view through binoculars. How big the coma is and the extent to which it interferes with your vision is critical to the effectiveness of your telescope.
* Planisphere. A fancy word for a star chart. It is nothing more or less than a detailed map of where everything is in the universe and how to find the star you want to study by taking off the known stars.
* Barlow. This refers to a special type of lens that you can buy to increase the magnification of your telescope.
* Do you know how science finds out how old the galaxy, stars, planets are, all this is also possible through these telescopes, these telescopes find out from the light falling on them, how much of this light is Sal is Purana.
These are some basic concepts of telescope operation. We have deliberately chosen the people you want to know to discuss binoculars wisely. But your education in the more complex aspects of astronomy and telescope design and operation will continue as long as you are a lover of astronomy, which we hope will last for the rest of your life.
