He visto este articulo en la agrupación astronómica de Sabadell, a la cual pertenezco y me ha parecido curioso y me gustaría probarlo aunque no tengo filtro de SII a ver si realmente funciona, básicamente seria hacer esta mezcla, para reproducir el color natural (rojo: H?+SII; verde: OIII; azul: OIII+15% H?).
Os dejo el articulo por si os puede servir de interés:

Re: Paleta Hubble, a color natural
Muchas gracias.
Vamos a intentar combinar los canales a ver que se obtiene.
Un saludo.

Re: Paleta Hubble, a color natural
Alguien dijo algo parecido allá por 2012.....
"If our eyes could see colors in this part of the electromagnetic spectrum, surely they would see these colors.
In NGC 2237 ionized hydrogen and sulfur are the two components of this area mostly hot gas, so we would tend to see orange red.
In the center circle, but this element is oxygen, so we would see teal .
This huge cloud of gas and dust born NGC 2244, this open cluster that lies at the center of the nebula and thanks to its heat and ionization enables the brightness of this gas.
This image was taken with a CCD camera in Ha (14 hours) OIII (14 hours) and SII (9 hours), 37 hours total exposure, from near the city of Valencia (Spain)"
