Dave Healey's observatory is about 12 miles S of Sierra Vista AZ, about 20-
25 miles to my E/SE. Not quite as dark as Sonoita but could be considered a
dark site..magnitude 6+ at zenith. He also has some film pictures in
Burnhams Celestial Handbook and a series of articles in the lates Astronomy
magazine.
