Hi Ryan, If you want to create lighting model like sun, that's not important how far away your sun model. I think you are creating a sphere for representing sun model and you use same coordinate position for sun model and light source position.
You can prefer allocate light source position far away from your scene and allocate sun model closer for your scene. That's not change your sun models lightening operation if you want to see sun model when you look above the sky :) Or with simple changing on manipulator home position setting, you can set your asked viewing frustum.
