Tulip Nebula sent on September 13, 2023 (10:51) by Mastropasky. 33 comments, 1371 views.  [editors pick] [retina]

Continuiamo il nostro viaggio intergalattico. Durante la notte di luna nuova del mese di Agosto ho rivolto il telescopio verso la Nebulosa tulipano (Sh2-101). Si tratta di una fantastica regione H II situata nel tratto iniziale del braccio di Orione (uno dei bracci di spirale della nostra Via Lattea) ad una distanza di circa 8000 anni luce. La sorgente energetica che eccita gli atomi della nebulosa è una potente radiazione ultravioletta emessa dalle brillanti stelle di classe spettrale O, in particolare la stella Simbad (HDE227018) la quale brilla al centro del tulipano cosmico. Altra peculiarità della foto è quello sbuffo di forma arcuata di colore bluastro visibile sulla destra della Nebulosa Tulipano. Ebbene, dovete sapere che quel “BOW SHOCK” è il risultato visivo dell'interazione gravitazionale tra un buco nero della grandezza superiore alle 14 masse solari, ed una stella super gigante blu HDE226868. Il disco di accrescimento del buco nero è alimentato dai gas della stella che, aumentando in modo vertiginoso la propria temperatura, riescono ad emettere raggi X. Il sistema binario denominato Cygnus-X1 è una delle sorgenti di raggi X più potenti osservabile dalla terra. Piccola curiosità! Cygnus X-1 è stata l'oggetto nel 1974 di una scommessa scherzosa tra i fisici Stephen Hawking e Kip Thorne, nella quale Hawking scommise che la sorgente non fosse originata da un buco nero. Il fisico britannico decise però di arrendersi quando, a partire dal 1990, i dati osservativi rinforzarono l'ipotesi dell'esistenza del buco nero Ecco i dati: Montatura Equatoriale EQ6-r pro (asta pesi maggiorata Geoptik) Telescopio: Skywatcher 254 1000 F4 Camera di acquisizione: OMEGON VETEC 571 C Correttore di Coma: TS GPU APLANATICO A 4 ELEMENTI Camera guida: ZWO ASI 224 MC Telescopio di guida: Skywatcher 70 500 Software guida: PHd2 Software riprese: N.I.N.A Filtri: OPTOLONG L-Ultimate (3 nanometri) Scatti da 300s per circa 6 ore e 25 min di integrazione Gain: 100 Flat: 50 Dark:16

Spectacular photo. I have an ignorant curiosity in astrophotography: colors such as red or blue (in another photo of the series) are visible to the naked eye or are they the result of filters that make radiation visible?

I understand very little about astronomical photography, but I have many notions and knowledge in the astronomical field and what you do are simply masterpieces, also detailed in the explanations and comments ... pearls..
