Would the thin atmosphere and absence of light pollution on Mars make for a fantastic night sky, or would martian dust/twilight spoil the view? Why don't we have broad night-sky pictures?

Martian astronomy has some advantages. The surface pressure is near 8 millibars — less than 1 percent of Earth’s surface pressure — meaning that atmospheric refraction is insignificant. One effect of that is the stars would not twinkle. Another is truly dark night skies. Twilight is sometimes very long, such that astronomical imaging needs to be at least two hours away from sunset or sunrise. But the brightest lights on Mars are Curiosity’s Mars Hand Lens Imager’s LED lights and ChemCam laser. And in the skies, the moons are much smaller and fainter than ours.
