Fantastic, Steve.

We're thrilled to see that your outer halo extends a very long way, and the central nucleus is quite small. We noticed that in our version, but hadn't seen it before in other folks' work. We commented that overly increasing contrast will both reduce the size of the faint outer halo and increase the size of the central nucleus, and that could explain why others haven't seen it.

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,
MnT
