So, I have been sitting on this data of M27, the Dumbbell Nebula, now since June. I have taken a couple of cracks at processing it, but with not much success. I was never happy with how it looked. So, today I decided to run it through APP and see how it comes out. I did most of the post process editing in PixInsight, but the subs were calibrated and integrated in APP. I also had Sii data on this object, however I still could not get a decent looking SHO image out of it, so I decided to just go HOO.
