Hi guys,

I saw some pictures from the pros have a combination of narrowband image to its LRGB image. I wonder how they put the narrowband channel together with RGB? Since there only 3 channels of RGB?

I know sometimes I notice that they put Ha layer as Luminance, but I think this one is totally different. Are they stacking the narrowband frame with one of RGB channel before processing in Photoshop/PI? If so, into what channel is preferable? Is there any special move to stack them?

I talk about nebula pictures that have blueish tint on it...

Regards,
