the first day of spring, the amount of time the Earth spends in light continues to increase, and the sun climbs to a progressively higher point each day. After three months, on June 22 or so, the summer solstice, the first day of summer and the so-called "longest day of the year,"...
lens or computer generated graphics onto hemispherical screens. Additionally, the lenses can be used in scientific photography such as studying canopy geometry, recording meteors and aurora, calculating near-ground solar radiation as well as in peepholes to offer a wide field of view to the users....
In order to describe the position of a star, a planet or any other astronomical objects, we need to use a well defined coordinate system. They might be a horizontal system which uses azimuth angle and altitude as a coordinate system, an equatorial system which uses right ascension and declina...
