Moon Watching There is a whole universe of objects to be seen in the night sky, so where do you start? The moon is easiest to find at night. When it is in its full position, when the entire surface of the moon is illuminated, it bathes the night in a silvery light, washing away all but the brightest objects from the rest of the sky. The best time to watch the moon isn't really when it's full, but any time before the first quarter, when the moon appears to be half lit. The Terminator on the Moon, the dividing line between darkness and light, shows the best features such as craters and mountains. Astronomical Use of a Reflector TelescopeAlways start observing through a 20mm eyepiece. This is a low-power eyepiece whose wide field of view will make it easier to search for astronomical objects. By the way, you will notice that if you look through a telescope, the stars still look like luminous dots, this is because they are very far away, even the largest telescopes show stars only as bright dots. After you find the object you are looking for, You can switch to a higher magnification eyepiece. You will notice that the subject will appear larger, but less bright, as if using a 20mm eyepiece. This is fine. If you observe in unsuitable conditions, the high magnification image may be fuzzy and unstable. If this is the case, switch back to 20mm. eyepiece, and try a more powerful eyepiece another time. Higher magnification can be obtained by inserting a 3x Barlow lens between the telescope and the eyepiece, this triples the available power. 1) How far can I see? If you stand outside and look at the night sky on a clear evening, you can see hundreds of stars without the help of your telescope. A telescope is a light-collecting instrument that magnifies an image, providing much more detail and revealing more stars, nebulae, and celestial objects. With a telescope, you can enjoy breathtaking views of Saturn's rings, Jupiter's major moons, the Orion Nebula, and more.2) Why can't I see anything with my telescope? object to be viewed, it is very likely that you are using an eyepiece that is too powerful. To solve this problem, always start with the lowest power eyepiece and only insert the high power eyepiece after you have located the object. 3) When I use the high power eyepiece, everything looks much darker. Why? As the magnification in the telescope increases, the brightness decreases. Conversely, brightness increases as magnification decreases. If the image appears too dark or fuzzy, use an eyepiece with a lower magnification. Small bright objects are more visible than large, dark or blurry ones! Atmospheric conditions, air currents, and light and air pollution also affect viewing quality.4) When I look through my telescope
