Nevertheless, many galaxies are perceptible even in binoculars. However, you will see, even with averted vision, not much more than a fuzzy star, and a washed out light spot or a short line, depending on the orientation of the galaxy. Only very few galaxies seem impressive at low magnification.<\/p>\n<figure id=\"attachment_250\" class=\"wp-caption aligncenter\" style=\"width: 400px;\"><a href=\"http:\/\/freebook.fernglas-astronomie.de\/wp-content\/uploads\/2014\/04\/M104.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-250\" src=\"http:\/\/freebook.fernglas-astronomie.de\/wp-content\/uploads\/2014\/04\/M104.jpg\" alt=\"Die meisten Galaxien erscheinen nur als kleiner Strich oder als verwaschener Stern.

M104 is one of the brightest edge-on galaxies.<\/figcaption><\/figure>\n<p>But there are exceptions where the binocular is clearly superior to the telescope. The Andromeda galaxy M\u200931 is our nearest big neighbor galaxy and only 3.2 million light-years away. In the sky it appears about 3\u00b0 in size, which corresponds to six times the full Moon. Only with binoculars or a very short focal length telescope you have a chance to see it in full extent. Under dark skies it is quite good to see, and its two companion galaxies are also in the range of a pair of 10\u00d750 binoculars. The Triangulum Galaxy M\u200933 in the constellation Triangulum with more than 1\u00b0 diameter is a very difficult goal for a telescope, while quite feasible in binoculars \u2013 but again only if the sky background is dark enough. In general, galaxies need some observation experience \u2013 they aren\u2018t very striking visually.<\/p>\n<p>Those galaxies where we look from the top down onto the spiral arms are called face-on galaxies. If we can only see the edge, they are called edge-on galaxies.<\/p>\n<p>You need a very dark sky to be successful when hunting galaxies. You won\u2018t have any luck close to cities, or you will see nothing more than the nucleus as a dim star.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Although galaxies are made up of billions of stars, they are also several million light-years away and therefore very faint.
