Apparent Motion

(religion, spiritualism, and occult)

It has become astrological tradition to speak about the zodiac and the heavenly bodies as if they were revolving around the Earth while Earth remains stationary. So that other people do not regard astrology as locked in a pre-Copernican worldview, astrologers sometimes specify that they are talking about the apparent motion of the stars and planets. In this custom, astrologers are following the same tradition as everyone else who refers to the daily appearance and disappearance of the Sun—for example, as the “rising” and “setting” of the Sun—even though most people in industrialized societies know that it is the axial rotation of the Earth that causes this apparent motion.

* The most important piece of equipment that astrophotographers need to move into the exciting field of deep-sky imaging is a tracking equatorial mount that allows their cameras and telescopes to follow the sky's apparent motion during long exposures.
Mackenzie and Bingham (1985) reported that apparent motion influenced the association between IT and Wechsler IQ.

RDK form detection involves the processing of apparent motion. Succinctly defined by Petersik (1989), "Apparent motion is the experience of motion that occurs when at least two spatially separated stimuli are alternately presented to an observer over time" (p.
In addition, the D810A has inherited a number of functions from the D810 that are convenient for astrophotography, including the ability to enlarge the view through the lens displayed in the camera monitor during live view up to approximately 23x to facilitate accurate focusing, an electronic front-curtain shutter that thoroughly suppresses mechanical shake, and a continuous shooting function with no limit on the number of shots possible for creating beautiful star trails (apparent motion of stars around the Earth).
