Apollo #5

Canaveral NS

20.81 SQM
Bortle Class 4

"Set up in the middle of parking area at Apollo #5. Lots of fire smoke during the day and into the evening from wildfire to the SW towards Orlando. Smoke visible throughout the evening along the horizon from the north to the west and south. The worst of it was over Kennedy Space Center. This location provides a nice option for relatively dark skies, given its more remote location from developed areas. There were constant airplanes visible, probably going in and out of Orlando."

Clingmans Dome

Great Smoky Mountains NP

20.8 SQM
Bortle Class 5

"A very windy night with strong gusts. FWHM definitely affected, probably by vibrations of the observation tower itself. Light polltion sources visible both in foreground and at horizon. A thin layer of haze evident to east, possibly part of approaching clouds. First data set virtually cloud free. Sky free of contrails. Limiting magnitude found in Pegasus. Andromeda galaxy visible, M15 requires much effort. Milky Way detail easily detectable near zenith. Sky appeared noticeably brighter than previous nights, possibly due to some airglow. I also think it may have to do with the atmospheric clarity. All other nights contained some amount of possible light absorbing clouds. The second set of images from this night do contain some clouds, but the first set is clear."

"This was a very clear night. High humidity. Trees covered all of horizon from this site, but light scatter was evident to the north and west especially. LZM found in Pegasus. Moderate Milky Way detail was visible. M31 easily visible, M33 a difficult averted vision object. Airglow likely strong."

Stafford Air Strip

Cumberland Island NS

20.54 SQM
Bortle Class 4

"Set up equipment on grass air strip just NE of NPS fire weather station. Numerous feral horses grazing nearby, though they did not seem interested in the equipment. This site provides a great location for stagazing, as the nearby light domes from communities and the Navy base are mostly blocked by the surrounding forest. Given the size of the cleared area around the landing strip, the tree line only extends to about 5 degrees above the natural horizon. For the nearby campground, this is an excellent area for visitors to enjoy the night sky. The light dome from Jacksonville is very prominent to the south and the Naval Submarine base also brightens the sky to the SW. The smoke from the previous days burning at the Navy base had subsided and the skies were very clear. SQM reading of 20.77"

Opal Beach

Gulf Islands NS

20.04 SQM
Bortle Class 6

"First night of data collection on our May GUIS trip. Setup went smoothly with a few clouds low on the northern horizon. Very high humidity but the lens stayed clear of moisture. Clouds to the north caused image 14 to misalign at first, but Jeremy manually placed it and processing was smooth after that. Pensacola light dome dominant to the west with the combined Destin/Fort Walton light dome to the east. Clouds moved in later. Only one set is usable."
