How does this version look on your monitor? There is quite a bit of detail but the noise or compression artifacts show up a bit.

Not sure what you meant by using Luminance in Red, wouldn't that skew the data, unless that's a common method.
Hello and thanks for making this effort with my image. On my laptop it looks a bit too bright, but on a friends Mac it looks better than mine, but the background look poor. This is the same problem I'm having when trying to proces my data from scratch on another computer. I'm not too sure why the sky values are proving quite so difficult. On my original effor the sky looked ok without black clipping, but not when I try to get a brighter nebula AND a dark sky.

My understanding of luminance data is that you can use any data you want for that channel....so, if red, (or Ha or red blended with Ha) shows more detail than the clear filter you can use it in place of the clear filter. So, in effect the RGB channels mostly provide colour into whateveer channel is placed in the luminance channel. My red channel looked way sharper than clear so I decided to go with red.....so: RRGB.
