Realistic atmosphere

I’m having one issue in regards to object scale with the Shader.

If my objects scale is too large, the Shader seems to stop working correctly - most notably the Sky Shader one. I basically have an inverted Sphere that I’m trying to apply one of the Atmosphere / sky shaders too, preferably the translucent one. As I move closer and further to/from the object for example, the atmospheres grows and shrinks and goes ‘inside’ the planet. (The mesh remains the same size of course).

I’ve just about got the Surface shader to work on my own planet surface, but the atmosphere not so much.
