Anders als Emissionsnebel sendet er kein eigenes sichtbares Licht aus. Stattdessen absorbiert und blockiert er das Licht der Sterne, die hinter ihm liegen. Dadurch erscheint der Nebel als dunkle Struktur vor dem hellen Sternenhintergrund der Milchstra\u00dfe.<\/p>\n<p>LDN 1235 besitzt eine Ausdehnung von etwa 15 Lichtjahren. Die markante \u201eHai-Form\u201c entsteht durch die Verteilung der Staubwolken innerhalb des Nebels. In seiner Umgebung befinden sich zudem mehrere Reflexionsnebel, darunter vdB 149 und vdB 150. Diese erscheinen bl\u00e4ulich, weil sie das Licht naher hei\u00dfer Sterne reflektieren.<\/p>\n<p>F\u00fcr Beobachter ist LDN 1235 \u00e4u\u00dferst schwierig zu erkennen, da er sehr lichtschwach ist. Seine Struktur wird erst durch lang belichtete Aufnahmen unter dunklem Himmel sichtbar.<\/p>\n<p>Entfernung zur Erde: ca. 650 Lichtjahre<\/p>\n<p>( Umrechnung: 1 Lichtjahr = 9,5 Billionen Kilometer )<\/p>\n<p>Die Aufnahme wurde von mir als 3 Panel Mosaik geplant und mit jeweils 14h 10min Belichtung pro Panel aufgenommen.<\/p>\n<p>[\/et_pb_text][et_pb_text admin_label=&#8221;Zur\u00fcck-Button&#8221;
