Free Planet Glow

I've been battling this since I started using Daz Studio.. how do I get a glowing planetary atmosphere in Iray?? Someone's probably already figured this out before me, but for those that haven't:

1.) Make a square Plane primitive. Apply the Iray Uber Base shader to it.
2.) In the Surface Editor, set the Emission Temperature to 10k, Emission Color to a light sky blue, and the Luminance to 20 kcd/m*2 (you can adjust these to taste).
3.) Use the attached file for Cutout opacity. Set to 0.5 transparency.
4.) Make the plane just slightly larger than your planet sphere and align them with the align tool. Turn off Cast Shadows on sphere(s) and plane.
5.) In the Constraints Parameter, set the dropdown (for the plane) to have it point at your main camera.

Voila! Hope someone finds this useful.
