Observing the Moon by a telescope. How to .

To film or photograph the Moon, there is no need to travel out of town to get away from light pollution. Indeed, in deep-sky astrophotography this is mandatory because using long exposures and you would not like the bottom of the picture (or all image), to have yellow spots or other colors of city lights that reduce sharpness drastically.

In general, for filming / photographing the moon, you need a clear atmosphere without turbulence from buildings temperature (in winter when people use thermal heat), because the Moon is bright and big, on which you are not using long exposures.

The first thing you do after installing the telescope and a camcorder / camera, is to find the Moon, which is not difficult, if you have a finder scope on the tube of the telescope (and most of them have one), to guide you in approximation toward it. Once you find it, you rub your hands, and open the camera. But it's blurry! You'll want to become clear on the display, and get your hands on focus, and rotate until the image becomes clear, then start surfing over various areas of the Moon to find an interesting region to film / photograph.

Images from the terminal, I have always felt are most special and more interesting compared to other moments of light, when craters are seen as normal, without any buzz.

-When the sun is at a low angle, lunar landscape becomes more realistic in most cases regardless of the region seen as the shadows of the mountains, craters, their central peaks and other forms of relief, to plan around them, thus obtaining more information in much greater quantity, of the area.

- When the Sun shines from a high angle, all is bright,without shadows of the relief, to give more life to the landscape.

Earth's Moon is "changing", not geological, but through light and shadow. Due to the phases of the Moon, we enjoy a unique show every evening, moonscape always having another look for those who have an astronomical telescope, large or small.

I have filmed some parts of the Moon repeatedly, but always I have noticed something new in it. I captured the moment when a crater was almost completely in shadow, times when it was in full sunlight, but also moments when the sun beats from various other angles.

Another factor that slightly changes the face of the Moon: often, the craters have "modified" a little in shape as seen from Earth, because the Moon libration because it does not stay fixed facing us, but has a periodic motion of inclination, like you see a child in the cradle.
