This is an LRGB image with NIR-blocked luminace and 6 nm Astrodon H-a data blended into the red color channel and the luminance to enhance the HII regions.
The image below is 1.25 hrs of H-a with a little wider field-of-view taken from my 12.5" RC in my backyard showing some of the detail in the HII regions. These regions actually have interesting shapes and structures including swirls and tendrils.
