Phys.org has just published a story, Pluto extreme close-up best yet:
These images, which were taken while the New Horizon's probe was still 15,850 km (9,850 mi) away from Pluto (just 23 minutes before it made its closest approach), extend across the hemisphere that the probe was facing as it flew past. It shows features ranging from the cratered northern uplands and the mountainous regions in Voyager Terra before slicing through the flatlands of "Pluto's Heart" – aka. Tombaugh Regio – and ending up in another stretch of rugged highlands.
The width of the strip varies as the images pass from north to south, from more than 90 km (55 mi) across at the northern end to about 75 km (45 mi) at its southern point. The perspective also changes, with the view appearing virtually horizontal at the northern end and then shifting to an almost top-down view onto the surface by the end.
The crystal clear photographs that make up the mosaic – which have a resolution of about 80 meters (260 feet) per pixel – offer the most detailed view of Pluto's surface ever. With this kind of clarity, NASA scientists are able to discern features that were never before visible, and learn things about the kinds of geological processes which formed them.
This includes the chaotic nature of the mountains in the northern hemisphere, and the varied nature of the icy nitrogen plains across Tombaugh Regio – which go from being cellular, to non-cellular, to a cross-bedding pattern. These features are a further indication that Pluto's surface is the product of a combination of geological forces, such as cryovolcanism, sublimation, geological activity, convection between water and nitrogen ice, and interaction between the surface and atmosphere.
[...] The most distant flyby in the history of space exploration, and yet we've obtained more from this one mission than multiple flybys were able to provide from one of Earth's closest neighbors. Fascinating! And what's more, new information is expected to be coming from the New Horizons probe until this coming October. To top it off, our scientists are still not finished analyzing all the information the mission collected during its flyby.

On July 14, 2015, at 11:49 UTC, the New Horizons space craft made its closest approach of 12,500 km (7,800 mi) above the surface of Pluto with a relative velocity of 13.78 km/s (49,600 km/h; 30,800 mph). This transpired at a distance of 4.5 light-hours from Earth, i.e. approximately 4.8×1012km away.

Pluto is a logical place for aliens to install surveillance equipment to gather close-up images of our solar system. Pluto is small, is distant from the sun, and orbits outside the ecliptic. Natives would be unlikely to look there.

Of course the aliens had to assume that one day a space probe might pass by and take pictures. Therefore they took pictures before building their base, and when they saw New Horizon was sent to Pluto (long before it arrived), they studied it, and when it arrived at Pluto, they deactivated its transmission to earth and replaced it by their own transmission, which contains the old pictures. Of course there's no way those earth people will ever notice, and it's even real Pluto images they get, just not the newest ones. After the images are sent, the probe's own transmission will be reactivated.
The Tao of math: The numbers you can count are not the real numbers.

and orbits outside the ecliptic
So does every planet but Earth (because its orbit defines the ecliptic). Pluto just has the largest inclination. How would that be a criterion in searching for aliens?

The large inclination of its orbit makes Pluto a better vantage point to spy on the planets from above and below the plane of the ecliptic.

The 40 AU average distance from Earth and 248 year orbital period, however, make it rather less than ideal.

Less than Ideal for what?
How closely do you have to watch a civilization that just two seconds ago (in relative terms) learned to land on nearby planets?
Perfect place. Comes close once in a while, stays comfortably out of reach most of the time.
No, you are mistaken. I've always had this sig.

Hiding in the clouds of a gas giant via blimp-like ships is also something to consider. It would take a lot of direct probing inside the atmosphere to run into such. Or perhaps radar, but radar is not considered effective for studying gas giants I believe. Probes go there to study air, not hidden blimps.

I thought all the alien's had bases on Neptune.
