Would it be possible to add a HA, OIII & SII selection in Trichromy for processing narrowband images. I know HA and SII filters are both in the red spectrum but making HA less red or even orange would help. As of now, I use Photoshop to change the green HA images toward the red.

Thanks,
Tony

Hi, in the Trichromy Window you may use the color matrix,
for example:
R -> 0.75 SII + 0.25 Ha + 0.00 OIII
etc.

Thanks for the reply. I have tried changing the values but haven't found the right combination yet. I will continue to try.
