By the time it became visible, and I was able to adjust I had time for about 6 pictures.
It is not visible or just barely with the naked eye. Tonight I was hoping it would be closer to the moon. A bit of distance between the two and it would have been barely visible with a wider lens.

This was shot with the 500mm and 1D IV.

Not great but here it is.
