[AZ-Observing] Re: FWHM measurements for Phoenix skies, anyone?

A lot of the Solar System objects are indeed best seen when the 
background is not "inky" black.  Some of the best views of Saturn I have 
had have been during twilight, or from my Tempe backyard, and not during 
the dead of night at a "really dark site", so I can indeed understand 
Pierre's comment.  I seems to be related to contrast ratio, and getting 
just the right ratio for the object under observation which means having 
a light polluted background for some objects.
