Last of Orion for this season... I was hoping for better color. I think I may have to re-think the ISO on this Nikon. Perhaps the 800 ISO was too much and I lost dynamic range.

Lost a lot of sharpness of this image when I published.

Anyway, it was a fun project and I learned a lot about this 180ED Nikkor. I will continue to mix in some wide-field imaging, lots of fun.
CS to all!
