Good detail throughout with Cygnus easily visible. M31 also visible to the naked eye. Oklahoma City easily visible to the east and Amarillo visible to the west.

INcredible bright LED panel mounted on top of NPS/USFS visitor center that is aimed sideways and plainly visible and creating shadows in the battlefield 1/2 mile west. Wind turbines to the SSW with blinking red lights (not too bad). Oil and gas installation 2-3 miles to the WNW with HPS unshielded lights. Local solar LED's at parking lot not working.
