Vrijedilo bi ponovo poku\u0161ati sa h-alpha filterom, no i ovako sam vrlo zadovoljan! Ekspozicije su bile 6&#215;5 min kroz luminance i po 4&#215;5 min kroz svaki od RGB filtera. Zbog nekih problema sam umjesto u Deep Sky Stackeru redukciju frameova (dark + flat) radio u CCDSoftu i ti se pokazalo kao puno, puno kvalitetnije rje\u0161enje!
