Update

Here I was using video  post to add effect such as blur , glows , spectrum lights and star-field.
However starfield failed render in my final animation background star did not work.

Heres it the lens effect I used on planet earth to create the sun , I then optimized the halos appropriately. 

On the camera I created a shaking effect using noise position this helped for a lot of my scenes.

 For example  when my ship was blasting into the worm hole I used it as emphasis of turbulence. This proved to demonstrate a effective method of portraying acceleration.

Here I have my UV map for the death-star I customised  the colour in Photoshop I wanted to create a death-star which camouflaged itself into space.
