Distance, time, and amount of light. All these things come into effect. The reason why Pluto took so long? Imagine trying to read a magazine with a pair of binoculars vs. somebody taking a picture right next to it. Which do you think will be easier to read?

We've had a pair of binoculars up in space for a while, but it was designed to see way further than Pluto. That is why we have always had blurry images.

We've had blurry images of Pluto because of its tiny angular size. The fact that its closer than some of the things Hubble has taken better pictures of is not relevant.

For example, here's a Hubble photo of Mars: https://milesobrien.files.wordpress.com/2010/08/mars_hubble....
