These four sketches show the evolution of Comet ISON over time during October-November 2013. At first, the comet was barely visible. No nucleus or dust tail could be discerned, but over time they became apparent. Each drawing is a stack of individual black and white sketches using the indicated filters. They were edited and stacked using Photofiltre and Canvas software.
