Don't underestimate the power of peripheral vision (averted vision). At sites near Penitas, looking slightly to the side of a faint nebula will reveal much more detail than looking directly at it, especially when dealing with the Class 5+ suburban skies of the TX region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 4 at Port Mansfield Channel (75.0 miles away) remains the benchmark for regional sky quality.

"Set up on the dune ridge adjacent to the channel and approximately 200 meters from the surf line. A couple of campers in the area, though not much in the way of lights. There are two lighted channel bouys (one red and one green) that flashed on and off. Some scattered low clouds to the SE and East. Port Mansfield light dome easily visible to the west and the developments on South Padre Island very bright to the south. The Milky Way was eaily visible though it was washed out in the SW horizon. M31 visible with the naked eye and stars visible to about 5 degrees above the ocean. This was still a nice place to experience the night sky, though skyglow to the south and west definitely impacted my observations."
