The primary direction of the system is the March equinox, the ascending node of the ecliptic (red) on … WebThe distance to the Andromeda Galaxy is immense: some 2,500,000 light years, but nonetheless its vast size and luminosity mean that it is still visible to the naked eye (in fact, it is the most distant object that can been seen without a telescope). Even so, much of the structure in its spiral arms is too faint to be seen, so that it appears smaller than it …
M31 right ascension and declination
Did you know?
WebRight Ascension : To point the telescope in a specific direction (using the “setting circles”, as it were), enter a right ascension and declination in the Aim Point boxes. You can enter right ascension in degrees; hours and fractional hours; or hours, minutes, and seconds. The following are all equivalent when entered in the Right ascension box: WebAccounting for the Solar reflex motion we deduce a relative velocity between Andromeda and the Milky way (in a non-rotating frame at the current location of the Sun) of 42.2 ± 39.3 km s−1 along right ascension (40.0 ± 39.3 km s−1 along galactic longitude) and −59.4 ± 30.3 km s−1 along declination (−60.9 ± 30.3 km s−1 along ...
WebAstronomy & Astrophysics (A&A) is an international journal which publishes papers on all aspects of astronomy and astrophysics Web25 nov. 2016 · The geographical latitude is the same as the declination, but to get the right ascension you will need to rotate your coordinates around the z-axis by an amount that is equal to the sidereal time at Greenwich ( θ G ). This is done, simply by replacing the the longitude (lon) with the sidereal time at your location θ = θ G − l o n.
