Default LRGB-filters true technology

Hello,

I use the LRGB filterset from tru technology.
For imagaing and processing, i use Astroart 4.0. When i set the trychromy
to 'auto' an d color balancing, then is get very red images. I image M27 a
couple of weeks agoo and the colors don't match.
So just wondering if somebody knows the coefficients for the RGB filters. I
use the SBIG ST8-XME camera.

thanks in advance,
Erik

calculate them. image an appropriately selected start and adjust the
coefficients so that it is white.
