Moving back to outer space, the HD70 does a very good job on the star field, with very little loss of stars compared to much more expensive projectors. It cannot however produce anywhere as black a "black" as say, any of the Darkchip3 DLP projectors (start at $2500 these days with the Optoma HD7100). the blacker the blacks the richer and more depth the scene has. Again, though performance for price is excellent. The more expensive Sanyo, Panasonic and Epson projectors can also do better, with their AI engaged, but to varying degrees.

Here's another pair - from Lord of the Rings, again, the first has a normal exposure, the second, overexposed to bring out details in the shed and bottom:
