When combining the luminance layer with RGB, it's supposed to help you end up with a smoother image - there's more light transmission in the clear L filter and so the gain can be a bit lower, or a higher frame rate can be used. So you can hopefully end up with a nice smooth monochrome luminance image, and use the colour data from the combined RGB image by using layers in photoshop.
For the 5x powermate image, I captured at 30fps for the Luminance and 15fps for the RGB channels.
However, it doesn't always work out that it gives the best image. My limited experience to-date is that the luminance channel appears softer, even though it's brighter. Interestingly, Bird said as much on another thread over on CN.
It might be to do with the altitude or poor transparency we have for Saturn at the moment.
Earlier this year when I first got the DMK (before I had colour filters), I captured monochrome for Jupiter with the DMK as the luminance, and used the colour data from a ToUcam capture, and combined them. For that image, it turned out great. The detail in the monochrome image was already there, and the colour data added from the ToUcam really looked great.
I can't find it right now, but i'll post it tomorrow.
