Why are there no stars on New Horizons images of Pluto I followed the New Horizons Mission a little, and saw among others this image of Pluto:



I wonder, why you can't see any stars on it. As far as my very basic knowledge in astronomy goes, I think you can even see stars during a "Sun-Moon-Eclipse" here on earth. So besides having here a spectacular "Sun-Pluto-Eclipse", I further more ask myself if that eclipse is even necessary to see other stars, as those pictures are already taken quit far away from sun, and outside an atmosphere.

Is that not enough to see stars? Or does NASA remove the stars from the images, before publishing them? (If so, why? Not to distract?)

Thanks for answers!
The answer by @mso is very good. Another contributing factor is the exposure time of the camera on New Horizons. 

The amount of light reflecting from Pluto is greater than that from the background stars. As a result the exposure time is set to achieve a good image for the desired target and detail required. 

Over the integration time the amount of light from background stars is not enough to register onto the focal plane and subsequent image. 

In order to get good pictures of stars one needs to integrate over long period of time while maintaining accurate pointing.
