\"outters-nicolas\"Une demande de Sakib Rasool. Extrait de son texte \u00ab\u00a0Tycho’s Supernova (SN 1572) in Cassiopeia: 00 25 15.12 +64 07 58.8
\nThis famous supernova exploded in 1572 and was reported by the Danish astronomer Tycho Brahe. This supernova remnant is very bright in radio and x-rays but its optical emission is very weak and faint. It apparently measures 8 arcminutes and for some unknown reason, there are no detailed optical images of it at all!! It would be worth doing a deep Ha image to see what is in the area. It contains no OIII emission.\u00a0\u00bb<\/p>\n

A vous de juger, la zone est difficile \u00e0 imager car mal plac\u00e9e chez moi \u00e0 cause de la pollution lumineuse.<\/p>\n
