How can I convert Right Ascension and declination to distances?
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 … Web22 oct. 2009 · Calculates azimuth and elevation angle in the local horizon system for a sky position given in equatorial coordinates (RA Dec J2000).
