Hi Larry,
The Halo for me is part of the shot in this case as it was created by the reflected light from the top of the dome. I assume that is what you refer to. I preferred the glow.
It may have been bit accentuated by the compression to jpg and color space shift from prophoto to sRGB.
I may go back and tune it down a bit once I print it.
If there is outline halo around the top, that is for sure do to the jpg compression as there is none in the original.
