Thanks, Interesting tutorial. I have tried Ha RGB with my DSLR. I followed a pixinsight tutorial to process the image. I found a stage where the RGB data was put slightly out of focus. I hate the amount of time spent on the RGB part as chances increase that something goes wrong, clouds come, humidity...and leave me with a B&W. I was actually thinking of increasing the ISO sensitivity of this stage to drastically reduce the exposure time. Increasing the ISO will make the image more grainy (so I try to use the best compromise between time and senitivity) but if then I soften it anyway and the detail comes from the L channel. Better spend more time on the L. I guess that this would be very much like binning without the resize factor. Another Idea I thought of was to take the L with the Ha filter and then try and take the RGB simmultaneously as the sensor is really a color. Not so sure about this one though, I started getting good colour when I started using LRGB and narrowband. Probably just a slip of the mind!
