Not sure why it wasn't more prominent, but for anyone else like that was wondering, "reaches" "zips by" and the other adjectives are indicating a distance of 2,200 miles. As a computer vision/imaging person, that's a pretty far look for a 75mm (~3 inch) mirror. It's like trying to take a picture of the Empire State building in NYC from Las Vegas with a tripod telescope.
Even with such a small primary mirror, New Horizons has a number of advantages. First, Ultima Thule is larger than Manhattan. Not exactly large, but certainly bigger than the Empire State Building.
Second, the mount is incredibly stable. There are basically no vibrations to speak of. As an amateur astronomer, I can tell you that the mount is one of the most important pieces of equipment in astrophotography. A mediocre telescope on a good mount will give good images. A good telescope on a mediocre mount will give mediocre images.
Third, the mirror itself is much better designed and manufactured than the average amateur astronomer's scope. Certainly better than any of mine.
Fourth, the sensor is cooled to very low temperatures, so it is way less noisy than the average consumer sensor.
Fifth, there is no atmosphere in the way. This is a huge advantage.
When all is said and done, LORRI will have a resolution on Ultima Thule's surface of about 60 feet. Certainly no Google Earth, but plenty good enough for the science objects of the flyby.
