Should have added this in the last post:

About Galaxies and other space stuff. Normally you have to stay above the ground plane to work on such, or delete the ground plane to remove it from view. That can cause a problem in relation to your sense of direction while working on a scene. Yes, you can look to the coordinate’s box, but that can throw you off if a visual person. 

 

This tip is a bit simpler to work with as you want the ground plane and World View Sphere visible so you can relate visually rather than have to check the X,Y,Z coordinates all of the time.  

 

Suppose I will make a nebula and want lots of real estate.  I flip my Main camera up 90 degrees to face the top of the World Sphere; you can use the Top camera, or create a new camera to do the same. 

 

Open Options, Display Options and unclick the setting Stop camera from going below clipping plane (groundwater).   Move the camera down to the bottom of the World View, you should be able to see all of the ground plane mesh in the Main View. Set the ground plane to 100 % transparent, do not delete the ground plane or the World View will disappear and you are stuck in space without visual references.   At least that is what happens in my Esprit.

 

You will find objects and lights will have to be quite a bit larger and brighter to work in this new added space, but you will have lots of real estate to work with for your scene.
