Doesn't mean it's not there just not concentrated away from the Ha enough, to delineate I think, The Ha in the same areas over powers it..? My recent M83 had some good signal in the OIII stack (I collected over 3hrs worth) but it was fairly diffusely distributed, all lined up with the Ha I guess so can't really tell in the final image, perhaps just an alteration towards a teal hue in the inner 50% of the galaxy..? Maybe why your final result is looking quite blue across the board too..?

Again, great project well done

Mike

Thanks Mike! from memory you're pretty spot on with the distribution of the O3 in this one. It's definitely present and mostly diffuse, and lends a nice amount of blue to the arms, but it's overpowered and out-shone by the Ha.



I may also have my blue saturation turned up a bit too high...

Thanks Dave!, I'm constantly surprised at how sharp the Tak can be when the skies are stable. I think I really lucked into some good weather when I was capturing this one.

Beautifully processed too
Well done !!

Thanks Martin! I'd not heard it referred to as Caroline's Galaxy before. A fitting reward for one of the great astronomers!
