"The universe is like a television show...we all came in the middle and no one is staying for the end." - John Dobson . Here's an image of the horse head nebula complex with a HSB color palette, my thought was that it's not worth going for oxygen in this nebula since there isn't any, and I'd get more color depth just shooting blue. Not a lot of integration on this image (maybe 9hrs). Let me know what you think!
