These images are LRGB composites, using a StarlightXpress MX5c color camera for the RGB information, and ST8 or ST237 for the luminance data. This technique allows relatively short, low-resolution RGB exposures to be combined with long-exposure detailed greyscale images which provide the fine detail and only take their color values from the map provided by the coarse RGB image.

My images were registered using Mira A/P and luminance/chrominance data combined in Photoshop4.

This technique is documented at Robert Dalby's web site, who was one of the pioneers of this technique in astroimaging.

Many thanks also to Terry Platt at StarlightXpress for his innovative and relatively inexpensive "one-shot" color cameras, which make color imaging enormously simpler and faster than conventional RGB imaging which requires separate guided exposures through color filters for each color channel.
