Da diese aber in der Helligkeit stark unterschiedlich sein, kann man an im auch die G\u00fcte des Himmels (=<a href=\"https:\/\/www.austrianaviationart.org\/cms\/seeing-wettervorhersage-fuer-sterngucker\/\" target=\"_blank\" rel=\"noopener noreferrer\">Seeing<\/a>) ablesen. Polaris hat eine Helligkeit von mag 2. Im Kasten der hellste Stern hat auch mag 2,1, der darunter mag 3,0. Die restlichen Sterne der Deichsel des kleine Wagen haben mag 4,2-4,4. Der schw\u00e4chste Stern des Kastens, schr\u00e4g gegen\u00fcber des hellen Kochab, hat nur mag 4,9 also fast 5, gleich dar\u00fcber ist ein Sternchen mit 5.5!. Wenn man den sehen kann, hat man schon eine recht dunklen Himmel. Unsere angepassten Augen sehen Objekte von ca mag 5,5-6,5. Letzteres in Europa wohl kaum mehr.<\/p>\n<p>Alleine die Stra\u00dfenbeleuchtung senkt die Sichtbarkeitsgrenze um 3 mag, die Lichtglocke \u00fcber der Stadt nat\u00fcrlich weiter. Das hat aber gerade f\u00fcr den Anf\u00e4nger einen Vorteil: Er sieht nur die hellsten Sterne und findet sich leichter zurecht. Auch bei etwas l\u00e4nger belichteten Fotos gehen meist die hellen Sterne in einem Meer von Lichtpunkten der schw\u00e4cheren Sterne unter. Deshalb habe ich obiges Fotos durch ein Weichzeichenfilter gemacht. Helle Sterne zeigen dann eine gr\u00f6\u00dfere Fl\u00e4che, auch bei l\u00e4ngerer Belichtung.<br \/>\nEin normales Fernglas (7&#215;50) steigert die Grenzgr\u00f6\u00dfe um ca +4mag. Dann kann man Sterne und Objekte noch bis ca. 9-10mag erkennen. Man sagt &#8222;ab 200mm \u00f6ffnet den Himmel&#8220;. So steigt die visuelle Grenzgr\u00f6\u00dfe auf 13 mag. Der Zentralstern im bekannten Ringnebel der Leier mit mag 14,7 ist aber nur noch fotografisch mit l\u00e4ngerem Lichtsammeln abzubilden.<\/p>\n<p>Polaris, der Polarstern liegt nicht genau im Norden, sondern etwas daneben\u00a0auf der gedachten Linie Richtung Kochab. Er umkreist den Himmelsnordpol im Laufe der Nacht. Wird die Achse der Teleskopmontierung\u00a0 genau auf den Himmelsnordpol ausgerichtet (=einnorden). Dann reicht es, wenn ein Motor genau diese Achse bewegt. Wer das genau trifft und wenn der Motor pr\u00e4zise arbeitet, wird das Fernrohr oder Fotoapparat immer genau mit dem Stern nachgef\u00fchrt. So gelingen dann Langzeitbelichtungen. Wenn das weniger gut l\u00e4uft, belichtet man entweder k\u00fcrzer und \u00f6fter, oder man ben\u00fctzt einen Guider, der anhand eines Leitsterns die Nachf\u00fchrung korrigiert. Dazu verwende ich den <a href=\"https:\/\/www.austrianaviationart.org\/cms\/mgen\/\" target=\"_blank\" rel=\"noopener noreferrer\">MGen<\/a> von <a href=\"http:\/\/www.teleskop-austria.at\/shop\/index.php?lng=eng&amp;m=2&amp;kod=MGEN&amp;skod=%2049&amp;om=Astrophotography\" target=\"_blank\" rel=\"noopener noreferrer\">Lacerta (Teleskop Austria<\/a>)<\/p>\n<p>An lohnenswerten Objekten gibt es im Kleinen Wagen zumindest in unmittelbarer N\u00e4he des Polarsterns nicht viele allgemein bekannte Objekte. Wir sehen hier weitab unserer Milchstra\u00dfe in die Tiefen des Universums. Wer aber sehr lange belichtet (mehr als 10 Stunden!), wird aber selbst hier <a href=\"https:\/\/de.wikipedia.org\/wiki\/Sternentstehung\" target=\"_blank\" rel=\"noopener noreferrer\">Molek\u00fclwolken<\/a>, wie sie \u00fcberall vorkommen, finden k\u00f6nnen. Solches herauszuholen ist aber eine hohe Kunst, meist reicht die Tiefe (sehr lange belichtet) der Astrofotos nicht, und oft werden die schwachen Staubb\u00e4nder beim Versuch den Hintergrund zu gl\u00e4tten gleich mit entfernt.<\/p>\n<p>Hier UMi\u00a0 um einiges tiefer belichtet<br \/>\n <div id=\"wppa-container-wrapper-3\" class=\"alignnone wppa-container-wrapper \" style=\"width:100%;clear:both;padding:0;position:relative;\"><div id=\"wppa-container-3\" style=\"width:100%;\" class=\"wppa-container wp-caption\"><div style=\"font-size:0;line-height:0\"><img decoding=\"async\" id=\"ph-817-3\" title=\"180408 Kleiner Wagen \/ B\u00e4r - UMi \" style=\"width:100%;margin:0;padding:4px;border:1px solid #777777;box-sizing:border-box;background-color:#cccccc;border-radius:5px;\" src=\"https:\/\/www.austrianaviationart.org\/cms\/wp-content\/uploads\/wppa\/817.jpg?ver=32\" alt=\"180408 Kleiner Wagen \/ B\u00e4r - UMi \" class=\"size-medium wppa-sphoto\"><\/div><div class=\"wp-caption-text\"><\/div><svg id=\"wppa-ajax-spin-3\" class=\"wppa-ajax-spin uil-default\" width=\"120px\" height=\"120px\" viewBox=\"0 0 100 100\" preserveAspectRatio=\"xMidYMid\" stroke=\"\" style=\"width:120px;

Das ist eine zuf\u00e4llig Anordnung von Sternen, die f\u00fcr uns einen Sinn ergeben. Die meisten Sternbilder sind das auch, denn die Sterne geh\u00f6ren nicht immer zusammen oder stehen in der selben Entfernung und haben gleiche Vorgeschichten. Die Sterne in diesem &#8222;Engagement Ring&#8220; haben eine Helligkeit von 8-9 mag, also eher nur mit einem gr\u00f6\u00dferen lichtst\u00e4rkeren Fernrohr zu sehen.<\/p>\n<p>Wer mal auf den Polarstern (Polaris) kurz belichtet (0,1-10 sek &#8211; je nach Ger\u00e4t) wird sehen, dass er ein visueller Doppelstern ist. Polaris ist mit mag 2 recht hell, der Begleiter hat nur mag 9.0 und steht mit 18 Bogensekunden (arcsec) recht nahe. Belichtet man zu lange, wird er vom viel helleren Stern \u00fcberstrahlt:<\/p>\n<p> <div id=\"wppa-container-wrapper-4\" class=\"alignnone wppa-container-wrapper \" style=\"width:100%;clear:both;padding:0;position:relative;\"><div id=\"wppa-container-4\" style=\"width:100%;\" class=\"wppa-container wp-caption\"><div style=\"font-size:0;line-height:0\"><img decoding=\"async\" id=\"ph-510-4\" title=\"18.8.2014 Polaris\" style=\"width:100%;margin:0;padding:4px;border:1px solid #777777;box-sizing:border-box;background-color:#cccccc;border-radius:5px;\" src=\"https:\/\/www.austrianaviationart.org\/cms\/wp-content\/uploads\/wppa\/510.jpg?ver=32\" alt=\"18.8.2014 Polaris\" class=\"size-medium wppa-sphoto\"><\/div><div class=\"wp-caption-text\"><\/div><svg id=\"wppa-ajax-spin-4\" class=\"wppa-ajax-spin uil-default\" width=\"120px\" height=\"120px\" viewBox=\"0 0 100 100\" preserveAspectRatio=\"xMidYMid\" stroke=\"\" style=\"width:120px;
