Caboose Farm
Catoctin Mountain Park
"Set up camera in field at Caboose Farm about 200 yds SW of Camp Round Meadow. Numerous direct glare sources from local farms and a building at Camp Round Meadow. A few clouds around the horizon to start but skies cleared completely by third set. Very high humidity along with warm temps causing high extinction. Sky glow from Frederick easily visible, as is the greater Baltimore-D.C. area. Milky Way is barely visible and most deep sky objects not visible. Decent view of most standard constellations and the night sky is still markedly better than from within Frederick or other comparable cities."
Murphy-Chambers Farm
Harpers Ferry NHP
"Set up on dirt road near canons at Murphy-Chambers Farm. Sky is cloud free at start of data collection with some low clouds along the horizon appearing later in the evening. Very nice location for night sky viewing, as this site is blocked from all direct glare sources. Milky Way is washed out in the lower sky from skyglow. Charles Town is easily visible to the west, the metro areas of Baltimore and D.C. have a light dome up to 30 degrees. For the most part, this area is surrounded by very bright skyglow along the horizon, though the natural terrain produces shielding that allows for comparatively good viewing. An SQM reading of 20.39 around midnight."
