Description

This is my first attempt at using Pixelmath to process an image. It was captured with a DSLR through a L-eNhance filter, then I used the scripts in Siril to split out the Ha and OIII as the basis for the formulas. The formula is very close to what BorealisLite demonstrates in his  Youtube tutorial.
