Here's my go, based on the original glowing sun file I had help on years ago.
As a TG Free user the first thing I do is up atmosphere quality to 32 instead of 16. Oshyan has mentioned no one should need to change this, but despite maximum settings of MPD 0.6 and AA 6 your atmosphere will be grainy in TG free. Two Atmosphere causes additional graining I've noticed. You can just place with the haze densities.
I'm not happy with the falloff on the ejection, would like to be more gradual. This is also internally illuminated, sun is deleted.
