Personally, I would not extract a Luminance master from the debayered image and therefore would not be using LRGB to recombine the Luminance again! I don't quite see the point of doing that and it is not conventional processing. As a beginner, I would try to keep things simple and concentrate on the essentials: get good data, get good calibration frames, find a good way of calibrating (personally I like to use PixInsight's own batch processing script). Then remove the light pollution, adjust the background, adjust the colour calibration and then try reducing the noise with TGV. Don't worry about using masks until you know what you're doing. Hope that helps! -
Without knowing the exact processing sequence you are using, it is difficult to be precise. However, your image does look very noisy. Also, I see that you turned up the colour saturation quite a lot when using LRGBCombination, which may account for the colour cast. At what stage did you use HDRMT? That needs to be used very carefully, and usually near the of your process. How much data did you have? Stephen

I saw your question on the ASA site about sky flats and Sequence. If you are still interested, I have managed to get this to work quite well on my installation at E-Eye. After setting up the filter sequence configuration file, you just click on "Dusk Flats" and then select the configuration file from the window which pops up. Do not press START NOW or START@TIME. As soon as the sun reaches 0 degrees, the mount will slew and start to make flats. Therefore, you do need to make sure that the roof/dome is open! In this mode, Sequence does not open the roof/dome automatically. (It would help if they told you that in the Manual.....)
The trick is to get the configuration file set up correctly. I have mine set to make dusk flats with the following filter sequence: SII, Ha, OIII, R, G, B, Lum. I make 5 exposures with each filter. That seems to work well in relation to the speed at which the sun sets.
Of course, if you want to make dawn flats, you need to reverse the filter sequence.
Hope that helps!
