Slight blurry-ness on the stars, no higher resolution than 4096

Hey there!

Discovered your excellent work in creating starry sky boxes. I'll be using some of the output in Vega Strike, if you don't mind. The singular stars do look a little blurry, and what with there being no atmosphere in space one would expect the stars to be hard points. This may be alleviated a little by enabling a higher resolution map to be downloaded. How difficult would it be to enable 8192x8192?
