I thought I would have a red hot go at this object. 9 Hours of luminance data and 3 hours of RGB (1 hour each).
Taken with W/O Flt 110 and using a QHY 9 mono at minus 20c. All LRGB have darks and flats applied. The second image is the rotated view and cropped of the first.
Great work, Mark! Some nice detail there. I'm sure you could squeeze a bit more colour out of it too if you push up the saturation in the brighter parts of the image.
