Description

Well, this came out a little soft on the detail. As it happened to be positioned over my neighbor's rooftop as it rose and then after it crossed the meridian it was positioned over my rooftop. Usually, my FHWM is 2.5 to 3.5. But, with this go around it averaged around 3.5 to 5.0.

The image is Bi-color RGB combine.
Imaged over 11/21/18 - 12/06/2018.
