Small refracting telescope and a cooled astronomy camera.
[Dwarf] planet Pluto was imaged on two separate nights ... I'm submitting 2 images, one from June 24 and one from June 27. You can see that Pluto has moved in front of the star background between those 2 nights. Most of the motion you see is actually from the Earth, not Pluto, since our motion changes our perspective of the much-closer Pluto against the backdrop of the much-farther stars. (Pluto is approximately 40 AU's from Earth, while most of the stars we can see with our eyes range from 250,000 to over 100 million AU's away).
