Accelerometer xyz anlges to ra/dec

  1. Jul 31, 2008 #1
    Hi !

    I have mounted a tri-axis accelerometer on a telescope which gives me angles for x,y & z axis, is there a method to convert these angles to the ra/dec or alt/az coordinate systems.

    Any help would be aprreciated

    Welcome to PF.
    Depending on how you mounted it - you should get alt-az directly, converting to Ra/Dec isn't hard (remember that for a given Ra/Dec the alt-az constanlty changes as the Earth moves)

    Try here http://seds.org/~spider/spider/ScholarX/coords.html [Broken] or if you can find a copy there is the famous "astronomy with your pocket calculator"
