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 or if you can find a copy there is the famous "astronomy with your pocket calculator"
