Hello,
This is my shot on Rosette in bi-color mapping.
My main interest is to show the dark nebulae and Bok Globules presents in Rosette, so that to have a better contrast of these structures, I decided to image Rosette in Narrow Band , using Ha and O3 filters.
The final image is not as smooth as normally Rosette is presented but shows the type of structures I was focused on.
The full resolution image is
