Description

This image of the cluster NGC2244 in the centre of the Rosette nebula was built up using a combination of narrowband and visual filters. I've used a mix of SII and Ha for red, as well as the red filter, mixed a slight amount of Ha into the green, and blue is OIII and B.

Although I haven't been very scientific about matching the exact hues of the narrowband filters, this has produced a much cleaner image than the LRGB alone.
