When is it important to know how to apply the notions of celestial orientation? Relevant cases are described below, although in essence, you interact with your concepts all the time every time you observe the sky, being of great help to optimize time.<\/p>\n

\"\"1st Case: Locate the South Celestial Pole through the Southern Cross constellation<\/strong>. In the Southern Hemisphere, one of the best-known constellations is the Southern Cross, not only because it is the smallest of the 88 official ones or because of the characteristic arrangement of its main stars (in the shape of a cross), but because, in the absence of a bright star located just in the direction of the south celestial pole<\/em> (unlike what happens in the northern hemisphere, with the star Polaris), amateurs must come up with some techniques to be able to find this imaginary point in the sky. One of them requires using the Southern Cross, as follows:<\/p>\n

\n

Project the "main mast" of the Southern Cross, 4 and a half times.<\/p>\n<\/blockquote>\n

\"\"As seen in the attached image, by making this projection (either with the help of a "green laser pointer" or with the help of the fingers of one hand), it will be possible to reach this location in the sky and use it to your own advantage, for example, when trying to capture an astrophotograph with the South Celestial Pole at the center (like the one in the example).<\/p>\n

<\/p>\n

\"\"2nd Case: Locate constellations according to the time of year and recognize their brightest stars<\/strong>When planning an observation, whether you are in the Northern or Southern hemisphere, it is crucial to understand the "behavior" of the night sky throughout the year, and to know that most constellations are only visible at a certain time, while others are visible all year round from our location (those circumpolar), or others are impossible to see from our location (those located at very distant declinations with respect to the hemisphere where one is located).<\/p>\n

In this way, gradually one will be able to understand that constellations such as Scorpio and Sagittarius are not only seen at specific times of the year (summer for the Northern hemisphere, winter for the Southern hemisphere), but also that in that direction one can contemplate one of the most striking areas of the night sky, as the center of the Milky Way is located there, as seen in the image.<\/p>\n

\"\"3rd Case: Interpret astronomical ephemeris in the context of attempting to observe them<\/strong>. It is often possible to find graphics from specialized websites, reporting on some astronomical phenomenon, or observational reference, which requires knowing concepts about how the sky is "divided" into its most elementary parts, that is, into degrees<\/strong>, minutes<\/strong> and seconds<\/strong> of arc. These concepts in turn allow us to understand the notion of "apparent size" (or angular size), which simply tells us "how much sky space" a certain astronomical object occupies.<\/p>\n

The above allows us to understand what those graphs mean that show the differences in the apparent size of Mars, when it is at a point in its orbit far from Earth, versus when it is in opposition<\/strong>, that is, at the closest possible distance to our planet. These differences in apparent size will be expressed, in this case, in seconds of arc<\/em>, as seen in the image on the side.<\/p>","protected":false},"excerpt":{"rendered":"
