3. Constellation Display of Entire Sky at 50 ° or 35 °North Right ascension scale Date scale Direction for turning constellation dial Zenith Horizon Ecliptic <strong>Celestial</strong> equator -18 altitude (twilight zone) Meridian Constellation dial setting Crown Time setting Normal position Because distortion is minimal in the northern hemisphere, approximately 98.5% of the celestial sphere visible at 50 ° or 35 ° north latitude is displayed. (The range shown on the constellation dials from -40 ° to +90 ° declination). The design varies from one model to another. 5.
4. Features The Constellation display includes the positions of 1056 fixed stars with a brightness of the 4.8th magnitude or brighter, 169 major nebulae,galaxies and star clusters, constellation boundaries and the ecliptic and the celestial equator based on their positions for the year 2000.0. (Maximum magnitude values are indicated for variable stars. Fixed stars are represented by a four colour spectrum at 0.1 magnitude intervals). The constellation dial not only automatically displays the present positions of constellations but can also be used as a planisphere dial in which the constellations dial is independently rotated. The solar position display shows the position of the sun along the ecliptic (the sun’s apparent path on the celestial sphere during the year) on the 1st, 11th and 21st of each month (for 12 noon universal time over the mean year). Times for sunrise and sunset as well as the number of daylight hours are determined by looking on the horizon line on the transparent dial. The altazimuth display lets you determine the altitude and azimuth of the sun as well as the major fixed stars, nebulae, galaxies and star clusters on the celestial sphere. (The equidistant almucanter lines at intervals of 15 ° on the transparent dial are corrected for atmospheric aberration. 6.
