The National Astronomical Observatory of Japan is in Hawaii? Boy, I’m gonna go find Mr. Small and punch him right in the nose! Telling all us gullible sixth graders America won World War Two. I suppose the Italians have a telescope in Florida and the Germans probably have one in New Hampshire.
The European Southern Observatory is in Chile. The U.K. is closing their observatory in Hawaii for financial reasons. A good site for an observatory is on a mountain top near the equator and as far from local light pollution as possible.
