Nebula Orion kawa diitihi pakai mata talanjang, biar diitihi di daérah nang kana [[polusi cahaya]] nebula ngini tatap kawa diitihi. Nebula Orion talihat nang kaya "bintang" di tangah "pedang" Orion, nang marupakan talu bintang nang baandak di salatan pandéng Orion. Bintang talihat kabur bagi buhan pangamat nang baisi mata nang hawas, wan nebulositasnya talihat jalas pas mamakai [[taroponh]] atawa [[téléskop]] halus. Kanyarakan puncak muka matan wilayah tangah adalah sakitar 17 Mag/arcsec<sup>2</sup> (about 14 [[mili]] [[nit (ukuran)|nits]]) wan nyarak kabiruan luarnya baisi kacarahan puncak parmukaan sakitar 21,3 Mag/arcsec<sup>2</sup> (sakitar 0,27 milinits).<ref>{{cite web
