Stessa rielaborazione della Nebulosa Rosetta!!!

Riprendo i concetti per chi capita su questa pagina senza aver visto la rielaborazione della Rosetta. In sostanza mi sono chiesto, cosa può accadere se applichiamo la metodologia biocolor di Steve Cannistra a due foto riprese entrambe in h-alfa, ma in tempi e con tecniche totalmente diverse.

Ovviamente per procedere servono 2 foto dello stesso oggetto con dimensioni lineari relativamente simili. Neanche farlo apposta il caso vuole che ho foto della nebulosa Pellicano fatte a 17 anni di distanza che si prestano allo scopo :-)

La prima è dell'altra sera effettuata seguendo le metodologie digitali correnti, la seconda invece è del 1999 (altra notte bellissima come non se ne vedono più purtroppo) ed è stata effettuata secondo le tecniche di quell'epoca utilizzando pellicola Kodal Technical Pan 2415 ipersensibillizata (home made) tramite cottura con idrogeno in camera a pressione e sviluppata con D19. Di seguito le caratteristiche:

Foto 1:
17/6/2016 Poggio Rusco (MN) 16mt, t=20°c, Sqm=18.83
Canon EF 400 f/2.8 L at f/2.8 with Baader 7nm H-Alpha
Canon EOS 60D CentralDS at 1600 ISO, ts=-5°c
Az-Eq5 guide with Lacerta M-Gen II on 50mm f/3.2
Integration: light 14x180”, 5 dark, 33 bias, 33 flat

Foto 2:
9/10/1999 Pampeago (TN)
Takahashi EM200
Canon F1
Takahashi FS128 a f/6
filtro Lumicon ha
pellicola ipersensibilizzata Tp2415
esposizione di 165'

Assumo che alla Foto 1 attribuisco il canale ha (prima riga dell'idrogeno), assunzione peraltro corretta secondo la metodologia classica, e quindi d'ora in avanti la chiamo pellicano-ha. Userò questo canale per la formazione del canale rosso della foto finale.

Alla Foto 2 invece attribuisco “arbitrariamente” il canale oiii (terza riga dell'ossigeno), e la chiamo pellicano-oiii. Userò questo canale per il canale blu della foto finale.

Purtroppo le due foto non sono di dimensioni ed orientamento uguali e quindi procedo (sempre grazie PixInsight) alla sovrapposizione delle due foto così da ottenere una nuova pellicano-oiii. Nel fare questa operazione purtroppo il campo inquadrato si riduce fortemente, non ho più il classico rettangolo 2x3 e questo da esteta mi dispiace un po', ce ne facciamo immediatamente una ragione :-)

Bene ora ho a disposizione pellicano-ha(canale rosso) e pellicano-oiii(canale blu).

Procedo a generare il canale verde tramite la moltiplicazione di pellicano-ha e pellicano-oiii. Ora ho anche pellicano-synthetic-green.

Il gioco è quasi fatto, ora procedo a fondere i canali in una unica foto secondo una modulazione di pesi che lascia spazio all'ispirazione soggettiva. Nel caso specifico ho preso il 100% del canale rosso, il 100% del verde e il 100% del blu. De gustibus….

Avanti con le critiche per favore!!!!!

Ciao

Marzio, I confess that after reading I went into the flask: -o .. nothing is worth the second try because my neural state is gone permanently block: -o I could get by with a random WOW pretending to understand but I would be a dishonest .. but from the work we've done shows an enormous intellectual genius work now WOW there may also be: -o :-D Great!

hello Marzio meanwhile thanks for having mentioned .... for your picture I can tell you that in this branch of photography also for fun, as you say, things can take a look nice and under some interesting point of view ... regarding this tell you that the detail there is to sell maybe that's missing is a signal bit more .... I would reiterate that with this kind of recovery in Ha exposures can also be stretched to more than 10 minutes in order to enable the sensor to capture more signal possible given the tight band of the filter in use and give you a way to manage without doing somersaults PP ... ;-) ;-)
