LRGB stacking processing in Siril 1.4.1 on Mac

Introduction

Three months ago, I wrote an article on color compositing LRGB images captured with RicoRem-Ricoh’s remote telescope . Targeting NGC 1566, I stacked multiple images exposed with each LRGB filter. For my own reference as well, I summarize the processing steps here.
