I believe it is too good to be true. I too have strived to capture such an image and have gone to a lot of effort to find such a tree in the foreground, plan a location to shoot from such that the scale of the tree would be about that of the diameter of the moon. One of the tricks is getting far enough away (about 1 mile for a 50 foot tall tree). This requires at least a 500mm lens, and ideally with a TC. You also have to plan on being in the right position at the right time, which requires careful use of a compass. Even then it is difficult to be exactly right when the moon starts poping up over the horizon so you need to be prepared to grab your big lens and run and resetup. When it starts rising you only have a few minutes before it passes up above the tree. And if you can get lucky enough to be in position and setup, you still need to get the focus proper such that you have enough depth of field between the tree and the moon. Because of the speed of the moon's movement past the tree, you will be limited as to the maximum aperture while still having enough exposure for the moon.
The attached photo reflects my efforts in this endeavor, captured with a 500mm f/4 with a 50D at ISO 800, f/8, and 1/30sec with quite a bit of cropping. As you can the sharpness is not even close to what Peter Lik has captured. I would imagine he would have needed at least 1/250sec to get enough sharpness on the moon. Theoretically you could get the hyperfocal distance at f/11, so you would probably need an extra 4 stops of performance compared to the photo I have here. Given the Canon 50D is little long in the tooth, more modern cameras would be better, but the sharpness of this photo seems hard to fathom given either the magnification, implying an even higher aperture to get the necessary hyper-focal distance relationship or a sensor of remarkable performance.
Also as some other posters have commented, this would have to have been taken just after sunset. Judging from the sky it looks about 45 to 60 minutes after sunset. The stars would not be this bright, especially with a full moon.
