It depends on what kind of device you have.And if you have a telescope, it's better.Without telescop.This simple metod is to straighten the camera to the Moon and hit the buton.But matters what settings you gave to the camera.With the mobile phone cameras would come out of the question to make something nice.They don't have an optical zoom, but digital.The difference between the two of them is that with the optical zoom lens, is the same as you would move to the object and take a picture.Instead, the digital zoom, increases your digital pixels, instead of approaching to the object, with the effect of "collapse" of the picture.The pixels are seen increasingly bigger as you zoom and the photo will not be so clear.
So it's very important to have an optical device that approach, not digital.The only way to take beautiful pictures is to not zoom, and the Moon to be already close, so it is recommended to be used only by the eyepiece of the telescope through which the image is already good in the front of your camera.And if the device (even as mobile phone), has some more megapixels, the picture can get really incredible.
With an optical zoom camera, the pictures come out more better(not always).The moon is clear.Fixed on the tripod to be stable, and the settings you need, you would like what that camera will do.Of course, digital cameras are now in vogue.Do not confuse digital zoom,with  digital camera.The digital camera has optical zoom lens (attached or not), these two things are different.
    The best to take in consideration in s
ettings of a digital cameras with optical zoom DSLR (digital single-lens reflex), is in my opinion ISO light sensitivity that is entering into the camera, and the exposure time.Who has a camera or a phone camera, can see ISO in options menu .
If the ISO is set lower, when it is dark, the resulting image will be the same as darker.but when is set bigger,the picture will be brighter, even if it's dark.
Exposure time.In photography, shutter speed is a common term used to discuss the exposure, that is the actual length of time of exposure to light on the sensor.More the CCD is open to light ,The more the picture is even brighter when is dark, releasing details that not even your eyes can see at that moment.
The telescope images can be made focal and afocal.Focal means to mount the camera without any objective, directly to the telescope,and take pictures through the ocular.Afocal pictures are achieved when you mount your video or photo camera in front of the telescope's eyepiece.
