Description

The classic target but once others pointed it out, I no longer see a horsehead but rather a headless muscular man walking towards me.  This is 5 hours of data shot with a OSC and a dual narrow band filter. It was processed in Siril using the "extract Ha & OIII" script and this image is the result of applying the post processing in Siril and Affinity Photo to only the Ha (hydrogen alpha) results file. I like the B&W look of the image although it's a bit soft in the Flame and a bit sharp in the stars.
