This new tutorial workflow for PixInsight is another post-processing example, this time of the Eastern Veil Nebula. It is based on LRGB. One of the unique features of this tutorial is that much of the image space is occupied by background and thousands upon thousands of small stars. Due to these two features, rather than crop, we exercise caution when it comes to noise reduction in order to avoid over-doing it. This is in line with the general recommendation that it is generally better to leave some noise present instead of trying to eliminate it completely (for a better end result). Moreover, since so many stars can over-power faint, diffuse nebulosity, we perform a star size reduction procedure in order to reduce the star sizes across the whole image and increase contrast on the nebulosity. Credit for the specifics of this procedure go to Rogelio Bernal Andreo (credited in tutorial as well).
