The moduli space of K3 surfaces XX with a purely non-symplectic automorphism \sigmaσ of order n\geq 2n≥2 is one dimensional exactly when \varphi(n)=8φ(n)=8 or 1010. In this paper we classify and give explicit equations for the very general members (X,\sigma)(X,σ) of the irreducible components of maximal dimension of such moduli spaces. In particular, we show that there is a unique one-dimensional component for n=20,22, 24n=20,22,24, three irreducible components for n=15n=15 and two components in the remaining cases.
