The Rosette nebula is one of the objects whose name needs no explanation. Even its color is similar to that of a rose because, as most objects of this type, it consists mainly of hydrogen. Other elements are also present, which emit light at different wavelengths, so their colors add to hydrogen’s red. My goal was to show high color dynamics in blue oxygen and red hydrogen emissions so I used narrowband filters for this.
