About this image

The OIII filter used was designed for visual work and seemed to filter out too much light making it difficult to obtain the normal Hubble palette colours for the image and requiring lots of stretching of the OIII images before combining. I will next use the ZWO 7nm OIII filter (matching the H-alpha and SII filters) and hope to obtain a more classic looking image. The images were processed in Affinity Photo. The overall effect reminds me plasticine from my childhood when you end up with a muddy ball with coloured stripes in by mixing it all together!
