ok well here is what i think. get rid of the star feild... go look on the web for pictures of space... preferabbly big ones... the bigger the better. maybe even some taken by hubble. then stick that picture on to a spere... and make the sphere encompass your scene. you will now have a much more realisitic looking (mainly cause the picture is real) starfeild or space background. this is what i am attempting with mine and its working out nicely i think... also... those planets are awfully close together.
