Nice picture but unfortunately that's pretty heavily edited composite image

If it was shot on a real situation, for the FOV it'd require just about 1000mm tele with a 1.6 crop DSLR (the angular FOV is about 1.4 degrees as far as I can estimate) and the atmospherical clarity does not match that kind of distance.
Also getting a balanced exposure is not possible from that kind of setup; remember that the surface of the moon is in bright sunlight (exp. f8, iso100, 1/200s) and the surroundings are in near darkness...
