Dew Point Calculator

This little app is designed To calculate the potential for dew formation on
Optical equipment at night, such as telescopes and binoculars. Most weather apps will give the temperature and Relative Humidity (RH) for any given time. Using this data, one can calculate the likelihood of the ‘dewpoint’, that situation in which condensation will form. Simply enter the forecast temperate and humidity, and from that the Dewpoint temperature will be returned. As long as the air temperature is GREATER than the dewpoint temperature, condensation will not form.
NEW:This update now includes facility to choose either Fahrenheit or Celsius scale. Also an instructions for use screen and a 'Rationale' screen describing why this type of app is needed for more accuracy in your chosen location.
