Celestial Coordinates: My Telescope Series - Carson Optical

Celestial Coordinates are similar to earth's longitude and latitude and it's mapped onto an imaginary Celestial Sphere. The celestial sphere is an imaginary sphere that encompasses the entire earth. Its purpose is to locate the position of astronomical objects. It is the basis of the coordinate system. Your view of the celestial sphere depends on where you're standing on earth. The Celestial Equator is an imaginary circle created by projecting the earth's equator on the celestial sphere. Because the earth is tilted on its axis, the celestial equator and poles are also titled. The North and South celestial poles, are the points which earth's rotational axis would intersect the celestial sphere. The position of a celestial body are described by two angles, Right Ascension and Declination. Right Ascension is measured in degrees or hours, minutes, or seconds. Declination is similar to earth's latitude. The angle of an object is measured above or below the celestial equator. Declination is measured only in degrees. If you have an equatorial mount with setting circles and you've aligned it to the poles, you can use the Right Ascension and Declination coordinates to locate any objects in space. http://bit.ly/2J7vDXx CarsonOptical May 06, 2019 at 10:39PM
