My PixInsight tutorial guide for combining narrowband-RGB

This tutorial is not meant as a full workflow through PixInsight, but instead is a guide regarding the process of combining narrowband and broadband data. It is generally a well-known technique to combine data from Hydrogen-Alpha into the Red channel of an RGB colour image. This technique strongly enhances nebulosity across entire images, bringing out fine detail and producing more intense overall nebulosity. Oxygen-III data can also be used in much the same way, mainly with the Green and Blue channels of an RGB colour image.

This tutorial guide is based on an officially documented technique by Vincent Paris of PixInsight, instructing in the best way to combine Hydrogen-Alpha and Oxygen-III narrowband data with RGB colour data. The resulting images produce strongly enhanced nebulosity while maintaining realistic star colours. The data used for this tutorial is based on the M42 Orion Nebula.
