You have done well to capture the nebulosity using such a narrow filter on the color camera.
Its amazing how many people are doing narrow band work now using a color camera. Sensors have become so good, that DSLR's or OSC are able to do it easily, well, a little work may need to be done.
You can see the gradual focus shift as you move from the bottom left to the top right. Shame, cause you did well on the rest.
