Since I know that there are people that are already content with the media vp stars, I'll go ahead and provide the RGB color values for each star that is in the Wiki, in case someone would like to make a mission using one of these extra stars. That way nothing is forced upon any FS user, and they can have realistic stars with their correct hue based on their luminosity and spectral class.
If I knew how, I would change the brightness settings for each FS mission depending on what star is in the system. By far, Deneb would have the most blinding scenery, yet I am sure users will find it very annoying to fly around in such a luminous environment. It depends on what you all prefer.
You are completely right about a star's spherical emission, and I am all for realism as well. But I did say that I would like to see realism with an artistic touch. I do not want to get into why I believe there needs to be an artistic touch applied to the media vps as I do not want to start a debate over it, but no star should be exactly like another. Stars have differing luminosity types, spectral types, variability, rotation rates, radii, age, etc. and each one of these plays a part in defining the appearance of a star. I just think the uniqueness of a star should be applied, even if it slightly stretches the boundaries of realism such as visible corona and stellar surface. But as Raven2001 said, its all a matter of personal preference, and I want to make everyone content.
EDIT: Lense flares sound like a great idea, only if I knew where to find those files. I would also like to see how I could possibly make the "rays" rotate with the user. The problem is these "rays", which are pretty much flares, are a part of the corona and so this means I would have to rotate the corona as well. I'll think of something...
