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."
