With LRGB the RGB data doesn't need to always be razor sharp of course it's better if it is, but it's not critical. So if you think that the RGB data isn't up to par with your other data, then perhaps try using it for saturation rather than definition. Then use your luminance data for the details and if you didn't capture any then the HA data can be used instead.
To get this to work you may have to do a bit more Photoshop wizardry. However, it would be no more than having to painting everything in and since you're already experimenting, it just might be something fun to play with.

Thank you.
Yes perhaps you are right.
I could mask the stars in the rbg and still use the colour template.
I may do this as an exercise in furthering my understanding of what tricks one can pull off with photoshop ..after all this image was really only about doing that...I will perhaps find time on my hands and try what you suggest. Thank you for your comments.
