WebJun 1, 2024 · The declination of an object is usually given in degrees, arcminutes and arcseconds. Its right ascension, on the other hand, is usually given in hours, minutes and seconds. Here, one "hour" corresponds to 1/24th of a circle, or 15 degrees. One minute is then 1/60th of an hour, and one second is 1/60th of a minute. So as units of angular ... WebOne degree of latitude equals approximately 364,000 feet (69 miles), one minute equals 6,068 feet (1.15 miles), and one-second equals 101 feet. One-degree of longitude equals 288,200 feet (54.6 miles), one minute equals 4,800 feet (0.91 mile), and one second equals 80 feet. Illustration showing longitude convergence.
Since antiquity, the arcminute and arcsecond have been used in astronomy: in the ecliptic coordinate system as latitude (β) and longitude (λ); in the horizon system as altitude (Alt) and azimuth (Az); and in the equatorial coordinate system as declination (δ). All are measured in degrees, arcminutes, and arcseconds. The principal exception is right ascension (RA) in equatorial coordinates, which is m… WebUsing the appropriate equation, in inches or millimeters, resolution results will always be in arc seconds. Rayleigh resolution is calculated as 5.45 / Aperture ( in inches) or 138 / Aperture (in mm). Dawes resolution is calculated as 4.56 / Aperture ( in inches) or 116 / Aperture (in mm).
