Atmospheric stability at my primary site
(Littleton, Colorado) is normally very poor and light pollution is
severe. Consequently, the best images are usually made at remote
sites, like the Denver Astronomical Society's
EG Kline Dark Site
near Deer Trail, Colorado. Support dark skies at the
International
Darksky Association.
