M10-M12 region in grayscale
Western Ophiuchus contains a lot of low-intensity reflection nebulae. These are essentially colorless and make challenging targets. Use luminance frames only. More effective to add more of them than to try to add color. Better to take frames over several nights in order to avoid intensity distortion cause by exaggerated star haloes.
