My first attempt at LRGB. 

Made a few mistakes with the initial data so grabbed some more last night.

 

Got about an hour of Luminance,  20 mins of RGB and an hour of Ha. I have no idea how to use the Ha data in LRGB yet so thats the next job 🙂

Looking good, some nice detail in there. If you are processing with Pixinsight, combining Ha and RGB is straightforward using the NBRGBCombination script.

It's self explanatory. Load the RGB image into the appropriate box, the default Bandwidth is 100, I set it to 200, it seems to work well, but you can play around with that setting. The Ha goes into it's own box, set the correct bandwidth for the filter, I leave the scale at 1.2. Press the NBRGB button, you will see the preview, if you are not happy with the result, adjust the settings in the RGB bandwidth again and press NBRGB button once more. Once you are happy, press the OK button, and you will have a new NBRGB image. I found using linear images produces the best results.
