How to create the light and the environment for an outer space scene?

[victorbarbu1]

I've just modeled a space station and I want to render a nice scene of it in the outer space. I am using 3ds Max 2016 and iRay for this. I got an sIBL Milky Way HDRi and added as an Environment Map.

 

This is what I get on a simple render with iRay (a blurry image, for no reason):

 

 

Accidentally I rendered it with Mental Ray and the map was just as I wanted:

 

 

Now, I want this image to be clear in the background and I would also like you recommendation about what light source I should use for this (if it is possible that you gave me this tip). Thank you very much!
