Nébuleuse du homard (SH2-157)

Recommended Posts

Un champ sympa du homard avec la bulle et un rémanent de supernova tout bleu à gauche (répondant au doux nom de G111.7-02.1 dans le catalogue Chandra SNR).

J'ai galéré à la traiter et je ne suis pas très content du résultat (rouge très bruité notamment).
