Where can i get a image map of the night sky or universe?

[LutherPhillips]

That depends on what resolution you want. There are no high resolution image maps of the entire sky. Starry Night has a composite that is generated/rendered by software on the fly but most other planetariums paint the sky n the fly by co-ordinates and object type.

There are lots of hemispherical images available - but they tend to be somewhat distorted and very low resolution.
