Hi Mike,
Got a technical question for you. When you do your LRGB combine do you normalise the RGB or the LRGB first?

No, I do everything by eye really.
I do the RGB and LRGB combine in Astroart4 and I think in a pretty basic way. After preparing the aligned R, G & B frames (usually DDP and log stretch) matching them purely by eye I just use the RGB command to get the RGB then usually blur and up the saturation a bit. I then open the Lum and do the LRGB with a single click - pretty simple.
