What would the sky look like to a being inside the event horizon of a black hole?
Suppose it was possible to travel to inside the event horizon of a black hole safely. Also suppose said black hole is large enough that the curvature of the horizon of the surface of the central mass of the black hole is similar to that on Earth or perhaps the Moon, yet we are somehow able to hand-wave away the problem of the crushing gravity. Also, for simplicity, suppose our intrepid traveller has senses similar to those of a human, and no high-tech sensors (as are seen for example in Star Trek) are used.
Under such circumstances, if our intrepid traveller were to look "up" (away from the surface of the central mass) in a way similar to looking up at the sky on Earth or the Moon, what would s/he see? What would the "sky" look like?
Note that I am not asking about actually travelling to beneath the event horizon safely, or what anything would appear like to an observer at a safe distance outside the event horizon.

A couple of guys from the University of Colorado created a video simulating what it would look like to fall into a black hole, including passing the event horizon. They have several other simulations on their website.
You should also check out the renderings made for the movie Interstellar. They made a couple discoveries while getting the physics simulations right.
