A bright, beautiful Triffid with lovely fine detail and colour. Awesome! How did you use the narrowband data? As colour or luminance, or both?

Hi ben

It’s, both. I combined the HA with my lum data to give it more contrast. The HA to add more red and OIII to add more green and blue.

Nice work, Ben. It's difficult to keep the blue reflection neb looking good when blending Ha.
