Images of Pluto
When seen in a star field through a telescope, Pluto looks just like any other star. The images of Pluto below were taken on June 8th and 9th 2002. It clearly shows Pluto moving across the star field over a period of 24 hours.

This is a DSS [Digital Sky Survey] image of the region of sky pictured in this demonstration. Note that the program object [Pluto] is not seen in the triangular shaped asterism in the center of the photograph. [North is down and East is right]
To put this movement of Pluto into context: If you hold a 1 mm diameter grain of sand at arm lengths, it subtends a distance of about 0.1 degree. The distance that Pluto traveled over the 24 hours from the evening of June 7th to June 8th is about 1/50th of the diameter of that grain of sand!
