Giant Squid Nebula sent on October 16, 2024 (10:25) by Mastropasky. 48 comments, 2224 views.  [editors pick] [retina]

Ciao a tutti, amici! ? Ecco la mia nebulosa Calamaro gigante nella costellazione di Cefeo. Tra tutte le nebulose fotografate negli anni, questa mi ha veramente distrutto, sia psicologicamente che fisicamente. Questa nebulosa è stata scoperta solo nel 2011, e questo già la dice lunga su quanto sia tenue e apparentemente "nascosta" nel cielo stellato... Ci sono volute ben 31 ORE di scatti per tirarla fuori in modo più o meno "decente"... ? 31 ore suddivise in 5 notti di foto continue su quella frazione di cielo dove tutto si vedeva tranne che il calamaro blu, e non capivo se andare avanti o rinunciare... Alla terza notte stavo per gettare la spugna, ma la tenacia ha vinto! Posso dire di aver fatto bene ad insistere, perché la soddisfazione di vedere quel calamaro gigante di ossigeno terzo evidenziarsi sull'idrogeno ionizzato è stata troppo appagante. ? Parliamo un po' di questa nebulosa: sebbene appaia completamente circondata dalla rossastra regione a emissione di idrogeno, Sh2-129, la vera distanza e la reale natura della Nebulosa Calamaro sono state difficili da determinare. Una recente indagine suggerisce che la nebulosa in realtà si trovi all'interno di Sh2-129, a circa 2.300 anni luce di distanza dalla Terra. Coerentemente con questo scenario, il calamaro rappresenterebbe un deflusso spettacolare prodotto da HR8119, un sistema triplo di stelle calde e massicce, vicino al centro della nebulosa. In questo caso, il misterioso e gigantesco calamaro si estenderebbe fisicamente per quasi 50 anni luce! ?

Spectacular work, with a contrast of colors that is a pleasure for the eyes.
The description of the acquisition process and the characteristics of the nebula is useful.
I didn't even imagine that in this century we could discover a nebula within the reach of let's say "amateur" instruments. This really makes you understand the difficulty in getting her out of the dark.

Dear friend, thank you for posting this magnificent photograph. It was worth it: it is magnificent. :-or

At first glance I immediately noticed how difficult it can be for a photographer who wants to achieve such ambitious goals, as confirmed by the caption. In the end, a street photographer like me, in front of these works, feels small.
I therefore congratulate you on the patience and skill you have shown, rightly rewarded by the Publisher.
Good evening and nice to have seen you!
Renato
