When you enter any new field of science, you always come across a bewildering new language of technical terms to learn before you can talk to the experts. This is certainly true in astronomy in terms of terms referring to the universe and terms describing the tools of trade, the most common being the telescope. So to get us out of the first rule, let’s define some key terms related to telescopes to help you talk to them smarter.
The first area of expertise in telescopes relates to the types of telescopes people use. The three telescope designs that most people use are Refractor, Reflector, and Schmidt Cass grain Telescope.
* The telescope uses the refraction of a convex lens to focus light onto the lens.
* A reflecting telescope has a concave lens, which means that it curves inward. He uses mirrors to focus the image he finally sees.
* The Schmidt Cass grain Telescope uses a complex mirror system to capture the image you want to see.
* A binocular telescope uses a set of telescopes installed and synchronized so that your view of the sky is in 3D.
In addition to the basic types, other terms refer to parts of a telescope or the science behind how telescopes work.
Parallelism is a term that refers to how accurate a telescope is to give you a good, clear picture of what you are looking at. You want your telescope to have good parallelism so you don’t get a wrong picture of the orb.
* Aperture is the fancy word for telescope lens size. But it is an important word because aperture is the key to the power of your telescope. The expansion has nothing to do with it, everything is in the opening.
* The focus is the coating that holds the telescopic lens in place, or depending on what you will be looking at. The photographer should be steady and in good shape in order for you to get an image you can trust.
* Mounting and wedge. Both terms refer to the tripod on which the telescope sits. The mount is the actual tripod and the wedge is the device that allows you to attach the telescope to the mount. There is a stand and wedge to help you with an excellent viewing session and to protect your expensive telescope from falling off.
* An Altazimuth stand refers to a telescope stand that holds the device in place and makes it useful during a stargazing session. The mouth of the ultrasimulator allows the telescope to move horizontally (which is azimuth) and vertically. This way you have a full range to look at objects close to or directly above the horizon.
Eating has a different meaning to what we are used to, and that’s fine. A coma is the inconspicuous area at the outer edges of your vision through a telescope. The size of the coma and how it interferes with your vision is important to the effectiveness of your telescope.
* Earth. Great word for star map. It is nothing more than a detailed map of where everything is in the universe and how to find the star you want to study by removing known stars.
* Barlow. This refers to a special type of lens that you can buy to enhance the magnification of your telescope.
These are just some of the basics of how a telescope works. We deliberately chose the ones you need to know to speak telescopes smartly. But your education in the more intricate aspects of astronomy, telescope design and operation will last as long as you are a fan of astronomy, which we hope will be for the rest of your life.
