\"outters-nicolas\"Voici une image de cet \u00e9t\u00e9 avec la richesse des n\u00e9buleuses de la r\u00e9gion du Cygne et plus particuli\u00e8rement la n\u00e9buleuse de la Tulipe Sharpless 101 et plein de petits trucs bleus plus ou moins diffus.
\nL’image est l’addition de 60 h de poses avec des poses unitaires de 30 mn.
\nJe sais c’est long mais le r\u00e9sultat paye sur les zones autour de la tulipe.<\/p>\n<\/div>

Sharpless 101<\/b> (Sh2-101<\/b>) is a H II region<\/a>[1]<\/a><\/sup> emission nebula<\/a> located in the constellation Cygnus<\/a>. It is sometimes also called the Tulip Nebula<\/i> because it appears to resemble the outline of a tulip<\/a> when imaged photographically. It was catalogued by astronomer Stewart Sharpless<\/a> in his 1959 catalog of nebulae. It lies at a distance of about 6,000 light-years<\/a> (5.7\u00d71016<\/sup>\u00a0km; 3.5\u00d71016<\/sup>\u00a0mi) from Earth<\/a>.<\/p>\n

Sh2-101, at least in the field seen from earth, is in close proximity to microquasar Cygnus X-1<\/a>, site of one of the first suspected black holes<\/a>. Cygnus X-1 is the brighter of the two stars (lower star) in close vertical proximity just to the right of Sh2-101 in the image presented here.[2]<\/a><\/sup><\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n
