Moonlight is for the most part just reflected sunlight, so it's not surprising that the colors are very similar. Obviously it's much less bright, by a factor of 500k according to Wikipedia, but that's what this sensor is about.
You can get similarly startling images from a plain point and shoot camera by installing it on a tripod and taking long exposure shots of things. You need 30 to 60 seconds exposure, sometimes available as a "starry sky" scene mode. Architecture is particularly suited as it tends not to move around. :) Even a cheap, small, P&S sensor is much more sensitive to light when you expose for 60 seconds, all while being completely noise-free.
- theatrus2 14y agoThe sensitivity didn't increase by exposing it longer - its simply accumulating more signal over time. Many sensors are ill-suited to long exposures though. While they can do it, you end up with heat related issues (commonly manifested as stuck pixels and general noise). CCDs also end up saturating and spilling over to adjacent cells, making high dynamic scenes a challenge.
