L'Elmo di Thor Con i suoi poderosi venti stellari una stella rara e gigantesca, una Wolf-Rayet, ha plasmato il materiale di questa incantevole nube, creando strutture di polveri e filamenti gassosi. La Nebulosa Elmo di Thor, così chiamata perché ricorda nella forma l'elmetto alato del noto personaggio Marvel della mitologia nordica, si estende per circa 30 anni luce e si trova ad una distanza di circa 15.000 anni luce da noi. Le stelle di W-R sono massicce almeno 20 masse solari alla nascita, molto calde rispetto alla media, infatti, il colore è bianco-azzurro, e corrisponde a temperature superficiali comprese fra 30000 K e 200000 K (la temperatura superficiale del Sole è di 6000 k) Nelle foto si evidenzia il bagliore delle complesse strutture nebulari, in particolare nella tonalità bluastra che mostra l'emissione degli atomi di ossigeno nel gas brillante. dati di scatto: camera asi 183mc raffreddata a -10°c - telescopio rifrattore apocromatico 71 f7.

Very nice and well detailed. Can I ask you some technical details about the recovery?
