Description

This image was processed to bring to the fore the darker ejected material in front of the radiating OIII and HII gas. The material with subdued emissions, or perhaps just less density, shows most prominently at the top and bottom of the nebula, obscuring it. But close inspection shows it covering some of the "comet" structures as well.

The key to revealing these subtle, dim features was the ability to target just their color and luminance and adjust them separate from other nebular features.
