Where I live I think it would take years to get 55.5 hours of clear sky.
The BiColour long exposure image really works. I wouldn't be surprised if publishers come knocking at your door looking for more of your images to hit the books.
I chose to bring the striking OIII result to the foreground in this image while leaving the Ha to occupy the background. The 3nm OIII filter really does reveal incredible detail.
Fair to say I think that's the best planetary nebula image I have ever seen. I think that might include Hubble's Cat's Eye or Hourglass, and I just put them side-by-side to verify. Visually gorgeous, like a big blue eye looking back out the screen, but so much more as well. Superb!
