Second acquisition with my wide field setup, askar FRA400 with x0,75 reducer resulting in 280mm focal length
Ha : 90x5'
Sii : 12x5'
Oiii: 12x5'
RGB : 5x5x5 x1' for stars colours
Luminance based on Ha only
Close to new moon last week, I could get an additional night of Ha acquisition, adding 5 aditional hours of Ha that gave me a little more in everything, especially Luminance
I decided to keep the colours that came after my SHO composition + adaptation: I am playing with pixel math in linear / starless on a basic SHO composition
In particular, I kept the greenish-cyan on the right.
The hue variation on the Oiii area, from the green-cyan on the rigth to the light bleu with magenta trends on the left was aligned with the relative signal strength variation of (Sii versus Oiii) within Ha after the boost I gave them and I decided to keep it.
Perhaps you won't like this very greensih style, generaly I prefer my self darker blue, like the one I got from cygnus loop in HOO
But there, I liked this hue variation and colours in the SHO composition.
Feel free to give your personnal opinion on these coulours !
now it's time to go back to the 200mm newtonian
