Hi !
cos(alpha)*cos(beta)*cos(dtp)+(-sin(alpha)*cos(delta)+cos(alpha)*sin(beta)*sin(delta))*sin(dtp)+cos(alpha)*cos(beta)*cos(stp)+(-sin(alpha)*cos(delta)+cos(alpha)*sin(beta)*sin(delta))*sin(stp)+(-2*sin(alpha)*sin(delta)-2*cos(alpha)*sin(beta)*cos(delta))*sin(t)
= 2*X,
sin(alpha)*cos(beta)*cos(dtp)+(cos(alpha)*cos(delta)+sin(alpha)*sin(beta)*sin(delta))*sin(dtp)+sin(alpha)*cos(beta)*cos(stp)+(cos(alpha)*cos(delta)+sin(alpha)*sin(beta)*sin(delta))*sin(stp)+(2*cos(alpha)*sin(delta)-2*sin(alpha)*sin(beta)*cos(delta))*sin(t)
= 2*Y,
-sin(beta)*cos(dtp)+cos(beta)*sin(delta)*sin(dtp)-2*cos(beta)*cos(delta)*sin(t)-sin(beta)*cos(stp)+cos(beta)*sin(delta)*sin(stp)
= 2*Z
Please help me solve this for {dtp,stp,t} ( the parameters are real and
X^2+Y^2+Z^2=1 ).
Maple keeps getting inflated on this one :(

Using Maple 8 and solve({eq1,eq2,eq3},{dtp,stp,t});
I get a very long solution (including RootOfs) after ~10 minutes and 100MB of
memory allocation. This answer can be simplified considerably using simplify.
I did not yet make use of your 4th equation X^2+Y^2+Z^2=1...
