Message du PC : mise \u00e0 jour n\u00e9cessaire dur\u00e9e 1 heure&#8230;..Bon ok j&rsquo;ai le temps et je lance la mise \u00e0 jour. Une heure ils disaient&#8230;\u00e7a a dur\u00e9 quasi 5 heures. J&rsquo;ai bien cru devenir fou.<br \/>\nNuit consid\u00e9rablement raccourcie, j&rsquo;aurais aim\u00e9 ajouter encore quelques images aux 23 d\u00e9j\u00e0 r\u00e9alis\u00e9es avec le D2 (SII-OIII). <\/p>\n<p>Les joies de l&rsquo;informatique !<\/p>\n<p>Le but d&rsquo;utiliser les deux filtres est d&rsquo;extraire les couches HII, OIII et SIII. J&rsquo;ai ensuite combin\u00e9 avec les images captur\u00e9es avec le Triband Altair. Ensuite combiner HII et OIII obtenus pour r\u00e9aliser une image dans la palette HOO. Puis terminer par l&rsquo;utilisation de la couche SII coloris\u00e9e en jaune pour r\u00e9chauffer un peu le tout. Une sorte de palette SHO.<\/p>\n<p>L&rsquo;image HII est utilis\u00e9e en luminance.<\/p>\n<p>Les \u00e9toiles sont g\u00e9r\u00e9es s\u00e9par\u00e9ment par \u00e9viter les \u00e9toiles de couleur magenta tr\u00e8s \u00e9trange.<\/p>\n<p>Donc voici la finale : 41x300sec Askar D1 + 23x300sec Askar D2 +48x300sec avec le Triband.
