NGC7000 Nebula in different emission bands sent on November 27, 2018 (19:32) by TommasoRubechi. 6 comments, 495 views. [retina]

Arezzo, Italy.

Spesso in astrofotografia parliamo delle diversi emissioni degli oggetti, concetto molto tecnico e complicato per i non addetti ai lavori. Mi sono divertito a riprendere uno stesso oggetto (la nebulosa NGC 7000) con un sensore monocromatico e, usando vari filtri,a ricombinare 7 diverse immagini a colori sfruttando appunto le diverse emissioni gassose. Tale metodo è sfruttato per evidenziare le regioni che ad esempio emettono di più nella banda dell'ossigeno piuttosto che in quella dell'idrogeno. Se volete saperne di più ho scritto un articolo completo a riguardo, che alcuni di voi già conoscono, dal titolo "I mille colori di un sensore monocromatico" che potete trovare nel mio sito tommasorubechi.it La strumentazione usata è CCD monocromatica SBIG st-f 8300 con 7 filtri della Baader Planetarium (R; G; B; Luminanza; Ossigeno; Idrogeno; Zolfo) Telescopio skywatcher 80ED Montatura Skywatcher Heq5 PRO con sistema di guida.

All beautiful, unfortunately so cut do not make it singly. Personally I think I prefer the third and the fifth
the two last filters what are they?

Beautiful photos, as Daomao says, is born the curiosity to see the whole picture...

Understood, I had not connected the Hubble palette to the acronym. I really like to find color schemes,
you could try to preserve the orange and blue + White to give a green tint.
