Hi John,
It is absolutely great shot
and lot of fine details in there. I don't understand why you said : "
I would need 5 hours for the blue channel to reduce noise in the reflection nebula part" ! When I look your beautiful image, I don't see to much the noise and the blue colour is enough. Just the saturation to down and maybe the blue channel.
Thank you to share this image with us.
Regards
Franck
