Coin-operated optics

Landmarks and scenic viewpoints all across America and the world are
outfitted with coin-operated telescopes and binoculars. These wonderful
devices stand ready to satisfy the tourist's eye and are a vital part of the
road trip experience but could they also serve the star-starved traveling
amateur astronomer who, for whatever reasons, does not have a grab-and-go
scope available?


Here is some information on the telescopes and binoculars awaiting (a high
percentage of which are in very dark locations) as you motor across the
world:

1. The objective lenses range from 60mm to 120mm in diameter.
2. Magnification is around 20x.
3. Azimuth movement is generally 360 degrees.
4. Most are capable of obtaining a maximum altitude position of between 30
and 50 degrees.
5. Perfect thermal equilibrium is a given.
6. Those in the U.S.A. provide at least 90 seconds of viewing per quarter.


Some other interesting facts:

1. Weight of the total unit is around 100 pounds.
2. Cost ranges from as little as $2,000 to as much as $16,000 per unit.
3. Some are mechanically operated while others require a battery or
connection to an outside power supply.
4. Many will hold up to 400 quarters.
5. Viewing time on most models can be preset from 90 to 180 seconds.
