Thanks Pkay,
Absolutely Robert, previously I was just trying to use the L-enhance data with a luminance layer extracted to bring out the detail but found the more hours I put into it I felt the SNR was diminishing (this is not to say that a different setup wouldn't produce a better result) but then decided to add RGB data to the previous. What I noticed was I was able to push a bit more in processing without creating too much noise.
This is a total of 4hr x L-enhance + 2hr x RGB OSC data.
Also I use a Sharpstar 90 APO
