Abstract background or realistic space themed background?

I want to add a canvas realistic or close to realistic cosmic /galaxy background as the background for this abstract piece im working on, should I abandon that idea and just go for an easier abstract background with shapes and patterns like you see and if not how do I go about creating a space themed/galaxy background on white canvas since it's easier on a black canvas, I'm afraid I'll mess the whole piece up having to create a black acrylic background.. thanks
