Lastly, as I was packing it in I noticed Hercules rising high in the
east. I couldn't resist a look at good ol' M13, and after observing
faint tiny things all night it was a real treat! It simply sparkled in
a 4.8mm Nagler (425x), filling the field. It seemed to have two "horns"
of darkness emanating from it about 50% of the way out. I hadn't
noticed these before. Other than that, all I have to say is, "Oh My!".
