The North America Nebula, also known as NGC 7000, is a large emission nebula in the constellation Cygnus. It got its name thanks to its shape similar to the continent of North America. The nebula in the upper right is called the Pelican Nebula and lies at the same distance of 2590 light years. These nebulae are very faint in visible light, but especially the North America is one of the brightest nebulae at infrared wavelength. That's the reason, why I had so many unsuccessful attempts at taking this object with my stock Canon EOS 760D.
So since I bought a modified Canon EOS 1300D last autumn, I was looking forward to taking this beautiful region. It's a pity, that I managed to take only one hour of data last Saturday, but I hope there will be another attempt to add some exposures this summer.

He's back, albeit low on the eastern horizon, by the time he clears my neighbours roof it's almost daylight, so I've only got 45mins on him last night before the sun rose and I had to park up.

.
Quello che stai per vedere è uno degli oggetti più affascinanti e misteriosi che si possano incontrare nel cielo.
Lei è Ou4, la Nebulosa Calamaro Gigante.
Si trova nella costellazione di Cefeo, all’interno, o almeno secondo lo scenario oggi più accreditato, di una gigantesca regione di gas ionizzato chiamata Sh2-129, conosciuta anche come Nebulosa del Pipistrello Volante.
E già qui c’è qualcosa di incredibile.
Perché quando guardi questa immagine, sembra quasi di vedere un gigantesco calamaro azzurro immerso in un enorme oceano rosso.
Ma quella forma non è stata disegnata da nessuno.
È il risultato di gas, radiazione e processi fisici che avvengono nello spazio interstellare.
E soprattutto…
è incredibilmente debole.
La Nebulosa Calamaro fu scoperta soltanto nel 2011 dall’astrofotografo francese Nicolas Outters, mentre stava fotografando proprio Sh2-129.
E questo è uno degli aspetti che la rendono ancora più affascinante: un oggetto gigantesco, che occupa una porzione enorme del cielo, era rimasto praticamente nascosto fino a pochi anni fa.
NASA sottolinea proprio questa caratteristica: Ou4 è estremamente debole, ma allo stesso tempo occupa nel cielo una superficie apparente enorme, quasi equivalente a tre Lune piene affiancate.
Ed è proprio qui che entra in gioco l’astrofotografia.
Fotografare il Calamaro dalla città è una vera sfida.
L’inquinamento luminoso tende a sommergere i segnali più deboli provenienti dal cielo profondo e Ou4 è talmente evanescente che servono moltissime ore di acquisizione per riuscire a far emergere la sua struttura.
Per realizzare questa immagine dalla città ho raccolto complessivamente…
120 ore di acquisizione.
E ho utilizzato filtri a banda stretta per separare e raccogliere i segnali provenienti principalmente dall’idrogeno alfa, H-alfa, e dall’ossigeno doppiamente ionizzato, O III.
Ed è proprio l’O III che ci regala quella spettacolare tonalità azzurra e verdastra che rende riconoscibile il Calamaro. NASA descrive infatti la sua caratteristica forma bipolare proprio attraverso l’emissione dell’ossigeno doppiamente ionizzato.
Ma attenzione…
il colore che vediamo in una fotografia astronomica non significa necessariamente che l’occhio umano vedrebbe la nebulosa esattamente nello stesso modo.
Nel caso di Ou4 stiamo rendendo visibile un segnale estremamente debole, associato a specifiche emissioni del gas.
Ed è proprio questo che rende l’astrofotografia così straordinaria:
riusciamo a trasformare una luce quasi invisibile in una storia che possiamo osservare.
Ma adesso arriviamo alla parte veramente incredibile.
Per molto tempo gli astronomi non hanno saputo con certezza che cosa fosse Ou4, quanto fosse lontana e quale fosse la sua origine.
Uno studio pubblicato su Astronomy & Astrophysics ha analizzato in dettaglio la morfologia, le emissioni, la velocità del gas e la cinematica della nebulosa.
I risultati sono compatibili con un deflusso bipolare veloce e collimato, cioè enormi quantità di materia che si muovono nello spazio in due direzioni opposte.
E qui entra in scena un sistema stellare davvero particolare.
Al centro della struttura si trova HR 8119, un sistema composto da tre stelle calde e massicce.
Lo studio scientifico ha trovato che le proprietà osservate di Ou4 sono compatibili con l’ipotesi che il deflusso sia stato prodotto proprio da questo sistema.
In questo scenario, Ou4 si troverebbe all’interno di Sh2-129, a una distanza di circa 2.300 anni luce dalla Terra.
E se questa interpretazione è corretta…
il Calamaro sarebbe un mostro cosmico dalle dimensioni impressionanti.
Oltre 50 anni luce di estensione.
Significa che la luce impiegherebbe più di 50 anni per attraversarlo da una parte all’altra.
Per fare un confronto:
la luce impiega poco più di otto minuti per arrivare dal Sole alla Terra.
Qui, invece, servirebbero più di cinquant’anni per attraversare questa gigantesca struttura.
I ricercatori hanno lasciato aperta anche la possibilità che Ou4 sia una nebulosa planetaria oppure il risultato di un evento eruttivo legato a una stella evoluta.
Quindi il grande calamaro cosmico conserva ancora un po’ del suo mistero.
Ed è proprio questo che lo rende ancora più interessante.
E adesso guarda nuovamente la fotografia.
Quella enorme struttura rossa che avvolge il Calamaro è Sh2-129.
Il rosso è legato soprattutto all’emissione dell’idrogeno ionizzato.
E dentro questa gigantesca regione rossa…
compare quel fantasma azzurro.
Ou4.
Il Calamaro.
Una struttura così debole che, senza ore e ore di esposizione e tecniche fotografiche adatte, praticamente scompare nel buio.
E c’è un’ultima cosa che trovo semplicemente meravigliosa.
Quando osserviamo una nebulosa distante circa 2.300 anni luce, non stiamo guardando il suo presente.
La luce che arriva oggi ai nostri telescopi ha impiegato circa 2.300 anni per attraversare lo spazio.
Quindi stiamo osservando Ou4 com’era migliaia di anni fa.
Mentre sulla Terra cambiavano civiltà, imperi e generazioni…
dall’altra parte della Via Lattea, questo gigantesco fenomeno cosmico continuava la sua evoluzione.
E noi oggi possiamo finalmente raccogliere quella luce.
Con un telescopio.
Con una camera.
Con un filtro.
E con tanta, tantissima pazienza.
Nel mio caso…
120 ore di pazienza.
E con la Nebulosa Calamaro si conclude anche il nostro viaggio tra gli oggetti astronomici ispirati al mondo marino.
Abbiamo incontrato cavallucci marini, meduse, delfini, granchi…
e ora anche questo gigantesco calamaro sospeso nel buio della Via Lattea.
Uno zoo cosmico che ci ricorda una cosa straordinaria:
l’Universo non ha bisogno di inventare forme fantastiche.
A volte…
le crea davvero.

Helix Nebula (IC 7293), 09/03/2021
Headed up to my buddy’s property in Orofino Idaho last weekend for some light boozing and shenanigans with a bunch of friends. I took the telescope as well on the off chance there were clear skies, and I wasn’t too far gone to use it. On the first night I was able to capture this before skies and my brain got too hazy to do any more.
This is the Helix Nebula. For obvious reasons it is very often called the “Eye of God” nebula. It is found in the constellation Aquarius and is probably the nearest planetary nebula to our Solar System, located roughly 650 light years away. Based on its size, age and distance it is expanding in size at 19 miles per second. My back of the envelope math estimates that is as fast as traveling to the moon in under 3.5 minutes.

North America Nebula (NGC 7000) and the Cygnus Wall, 07/22/2021
Several weeks ago I set up the telescope in the driveway to work out some issues I was having. I pointed at an object in a region of the sky I could see between the trees for a few hours. I wasn’t thinking I was going to get an image worth sharing but after I processed it, I was pleasantly surprised.
This is part of the North America Nebula (NGC 7000). It is found near the star Deneb in the constellation Cygnus. It is one of the few nebulae that’s distance has been accurately measured. The Gaia astrometry satellite calculated 395 stars within the nebulosity to a precise distance of 2,590 light-years away.
The Cygnus Wall is the W-shaped area along the “East Coast” of the nebula and is a region of concentrated star formation. I think it looks like an eagle in flight from overhead.

The Veil Nebula Complex - (NGC 6960, NGC 6992, NGC 6974), 09/25/2021
I went to Ahsahka Idaho again last weekend but this time I just brought my small “travel” setup. This is just an astro-modified Canon DSLR, a 200mm lens and a star tracking mount. This system is definitely smaller, lighter and easier to travel with, but it is a bit more difficult to use and does not give the same results. But I enjoyed the challenge and had fun playing with it. I was able to spend one night capturing this region of the sky.
This is the Veil Nebula Complex. It is the remains of a Supernova that exploded between 10,000 and 20,000 years ago in the Cygnus Loop. This Complex covers an area of sky 36 times the area of the full moon.

Tamron 70-200mm
