Filtering in iPhone and sharpness, tint in Photoshop

The sky mostly behaved at tonight's Austin Astronomical Society's (Texas) public star party at Pedernales Falls State Park, Texas. There were about 60 guests who braved the chilly temperatures (chilly for Central Texas). I gave a 40-minute sky orientation and then the guests got to see Mars, Jupiter, and Saturn along with the Andromeda Galaxy, Pleiades (the Seven Sisters), and the Orion Nebula (late).
The Star Theater at PFSP has a Stone Henge-like formation marking off the four cardinal points. There's an obelisk in the center that is oriented so that a hole near the top points directly at the North Star, Polaris. The lazy “M” constellation above the obelisk is Cassiopeia which is the wintertime pointer constellation to locate Polaris.
I spent about 15 minutes taking various pictures with my iPhone to get Polaris centered in the hole. This is my best shot. I'm quite satisfied with it!
