At first, of course, our instrument for observing the sky is our eyes. But it is important that the amateur first become familiar with the night sky, before thinking about purchasing instruments. And this is relevant because we must think of the sky as if it were a great city, seen from above:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignleft\" src=\"http:\/\/austrinus.com\/resources\/img\/ojo_ciudad.jpg\" alt=\"Campo de visi\u00f3n del ojo (analog\u00eda)\" width=\"205\" height=\"135\" \/><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" src=\"http:\/\/austrinus.com\/resources\/img\/telescopio_ciudad.jpg\" alt=\"Campo de visi\u00f3n del telescopio (analog\u00eda)\" width=\"205\" height=\"154\" \/><\/p>\n<p style=\"text-align: justify;\">With our eyes we will be able to see without problems in the city, since we will have a wide field of vision (<strong>Figure 1<\/strong>), but if we then observe it immediately with a telescope, without first trying to orient ourselves and recognize the main details of the city, what we will see will be a smaller field of vision where we would easily get lost (<strong>Figure 2<\/strong>), and at the end of the day we would be underusing the instruments (and wasting the investment!).<\/p>\n<p>Below you will see some questions, so that you can ask yourself and have an idea of what best suits your case, before considering purchasing your first instrument or moving on to a more complex one. The list goes from least to most difficult:<\/p>\n<p align=\"justify\"><strong>1. Can you recognize the main constellations in the sky? Do I know the brightest stars? Do I have basic notions of celestial orientation?<\/strong><\/p>\n<p><strong><img loading=\"lazy\" decoding=\"async\" class=\"alignright\" title=\"Instrumental: Eyes\" src=\"http:\/\/austrinus.com\/resources\/img\/ojo_instrumental.jpg\" alt=\"Instrumental: Ojos\" width=\"89\" height=\"89\" \/>If your answer is NO<\/strong>: So it is advisable to wait a little before buying an instrument. Use your eyes to look at the sky and consult sky maps to find the brightest constellations and stars. Consult the best-known techniques to orient yourself in the sky and know the celestial coordinates. Train your eye to discriminate stars based on their luminosity and color. Recognizes constellations according to time of year.<\/p>\n<table border=\"1\" align=\"center\" bgcolor=\"#eee\">\n<tbody>\n<tr>\n<td><strong>If your answer is YES<\/strong>: Then you are ready to purchase\u00a0<strong><em>Binoculars<\/em><\/strong>, an instrument with a visual field smaller than the eye.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p align=\"justify\"><!--nextpage--><\/p>\n<p align=\"justify\"><strong>2. Do I easily locate planets, star clusters and nebulae? Can I discriminate stars with minimal luminosity differences? Have I spent time looking closely at the craters on the Moon?<\/strong><\/p>\n<p align=\"justify\"><strong><img loading=\"lazy\" decoding=\"async\" class=\"alignright\" title=\"Instruments: Binoculars\" src=\"http:\/\/austrinus.com\/resources\/img\/binoculares_instrumental.jpg\" alt=\"Instrumental: Binoculares\" width=\"89\" height=\"89\" \/>If your answer is NO<\/strong>: Then it is advisable to continue practicing with binoculars a little more. Practice slowly &quot;scanning&quot; areas of the sky and orienting yourself according to what you see with your eyes. Identify details of star clusters, the morphology of nebulae and the appearance of planets. Try to find faint objects that cannot be seen with the naked eye, using celestial charts. Compare the craters on the Moon with an Atlas.<\/p>\n<table border=\"1\" align=\"center\" bgcolor=\"#eee\">\n<tbody>\n<tr>\n<td><strong>If your answer is YES<\/strong>: Then you are ready to purchase a\u00a0<strong><em>Telescope<\/em><\/strong>, a visual field instrument smaller than that of binoculars and much larger than that of the eye.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p align=\"justify\"><strong>3. Should you target better-known Solar System and deep space objects? Can I move in a small field of vision and come back without getting lost? Do I have experience doing prolonged observations?<\/strong><\/p>\n<p align=\"justify\"><strong><img loading=\"lazy\" decoding=\"async\" class=\"alignright\" title=\"Instrumental: Telescope\" src=\"http:\/\/austrinus.com\/resources\/img\/telescopio_instrumental.jpg\" alt=\"Instrumental: Telescopio\" width=\"90\" height=\"90\" \/>If your answer is NO<\/strong>: Then it is advisable that you continue practicing with the telescope, a little more. Make a database with the most interesting objects and learn to locate them. Practice observing variable stars, nebulas, galaxies and faint clusters. Travel through various objects in a constellation following &quot;paths&quot; of visual clues with the stars. Observe asteroids, comets and other objects that require knowing their coordinates.<\/p>\n<table border=\"1\" align=\"center\" bgcolor=\"#eee\">\n<tbody>\n<tr>\n<td><strong>If your answer is YES<\/strong>: Congratulations! You are on a good footing to decide to purchase a\u00a0<strong><em>most complex telescope<\/em><\/strong>, O well\u00a0<strong><em>specialized accessories<\/em><\/strong>\u00a0for astronomical purposes, depending on the area you want to delve into.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p align=\"justify\">Do not forget that this guideline is only a suggestion, and it is always up to you to determine the best time to purchase a new instrument.
