Default Rendering - Creating a camera facing shader

I'm trying to create a nice planet with good atmosphere. I've made three concentric spheres, the smallest a planet skin, the next two slightly bigger than the last and i intend them to have camera facing shaders, so that the atmosphere is thickest around teh edges. I had managed this once in 4.0 but forgot how I did it. I'm in 5 now and a bit fuzzy on the use of render nodes for this. Any ideas?

Thanks..

You could use the Sampler Info node for this. Use it's facing ratio to control a Ramp's V coordinate and then the Ramp's color to control the shader's Transparency. Can't check right now but you may need to add a Set Range node between the Sampler Info and the Ramp to scale the facing ratio to 0 - 1 (it's -1 to 1 by default if i remember correct).
