We're hoping to get more Sombrero over the next new moon, optimistically starting with three hours tonight. Can we ask what exposure did you use, and what sized instrument?
Regardless, yours is one of the very best Sombero's we'e seen.
Best,

Thanks M&T. All the information is at the link for the image. It's a 14.5" RCOS Ritchey Chretien (previously owned by Don Goldman). The exposures were:
Luminance = 180m (unbinned), R = G = B = 70m (binned 2x2)
