A telescope is a great tool with which you can discover many new and amazing space objects. However, beginners are often disappointed when they can’t find answers to the questions of how to set up my telescope or how to use it at all. In order to see the target in all its beauty and see the details, you need not only a good telescope, but also the ability to aim it correctly. Therefore, in this article, I will tell you how to aim telescope to make your stargazing experience as simple and enjoyable as possible.
Aiming the Telescope Guide
- Identify the object and choose the place where you want to stargaze;
- Place your telescope on solid ground to secure it from unnecessary movement;
- Use atlases and maps to find the coordinates of the target;
- Practice pointing in the daylight using ordinary objects;
- Align the finder and use the lowest power eyepiece.
How to aim a telescope step by step
Aiming a telescope can be a complex and confusing process, especially if you are using it for the first time. That’s why I have prepared for you eight simple steps based on scientific knowledge and my personal stargazing experience.
Let us now consider each of the steps in more detail.
Step 1: Prepare your equipment
Before you start, you need to make sure that you have all the necessary equipment. The basic set includes the telescope itself, a tripod, tools for magnification (different types of eyepieces or a Barlow lens) and a finder. If you use a reflector telescope, you will need to align the mirrors before you start. You may even need to clean them. If you use a refractor, you do not need to perform additional alignment steps before observation. You need to mount the telescope tube on a tripod and secure it with screws.
Step 2: Learn the sky
Before you try to aim the telescope, you need to become more aware of the sky. Learn about constellations, planets, and their coordinates. Before that, you can observe the sky without a telescope, and try to find the main celestial objects in the sky in your area. Explore more theoretical information. Read books on astronomy to understand when and where it is best to observe the desired object. You can also start using special software, online maps to check the location of certain celestial objects relative to those you can see with the naked eye. However, if you like more traditional methods, try using star maps and atlases. They usually also contain detailed instructions on how to recognize less visible objects relative to those stars and constellations that are known and visible even without special equipment. Use red light to read star charts at night, then it will be easier for the eyes to get used to the darkness.
Step 3: Choose the location
If you think that location does not play a role in how to sight in a telescope, you are wrong. Because in order to aim a telescope easily, you need to choose the right place. First of all, keep in mind that the aiming process depends on how well you secure the tripod to the ground. That is why you should choose places with solid, level ground. It should also be borne in mind that concrete structures can cause problems with the temperature of the telescope, so they should be avoided.
The level of light pollution is also important. After all, if you live in a big city, the lighting level will prevent you from aiming the telescope properly. You can try to climb on the roof of a high building. This will reduce the level of light pollution. But do it only in safe places, do not neglect your safety.
Step 4: Practice in the daylight
Many beginners, after buying a telescope, think that the process of observing the stars should begin only at night. However, this is a misconception because, in order to aim well at night, you must confidently use a telescope. And if you want to learn how to better aim the telescope, you need to practice during the day. Because at night, due to the darkness, it will be harder to navigate in space and use the telescope itself. You need to practice aiming.
You can adjust your telescope and select a specific object by using the lowest power eyepiece. However, you cannot aim at the sun. It is very dangerous and can damage your eyes. You can set the main sight at about 80-100 feet. Place the object in the center to make sure it looks clear enough. You can then switch to the higher power eyepiece and try to repeat all the steps again to keep the subject clear and sharp.
Step 5: Choose the object
In order to aim properly, you need to understand exactly what you want to observe: planets, constellations, or galaxies. Because it depends on the time and place of observation and focuses adjustment. For example, if you want to observe the planets, you must first check the time of the rise of the planet in your area. Watching Jupiter is always fascinating because it is a large and bright planet, the details of which can be clearly seen with the right chosen time and adjusted telescope.
If you want to watch the stars, consider the phase of the moon. The full moon will prevent you from aiming at other less bright celestial objects due to its powerful light during this phase. Also, keep in mind that different telescopes have different uses. If your goal is to observe the moon and nearby stars, then given the high contrast, a refractor is a more appropriate choice. However, if you want to explore faint celestial objects and nebulae, you will need a reflector telescope with a larger aperture.
Step 6: Use the right eyepiece
The eyepieces are one of the first accessories for the telescope that a beginner should learn to use. The eyepieces have different diameters, so by simply replacing them, you can achieve a significant increase in magnification. The eyepieces have different powers. To see it, look at the number on the eyepiece. The higher the number, the lower the power of the eyepiece.
The observation and aiming should always start with the eyepiece with the lower power. It is easier to focus on due to its wider field of view. However, remember that as the power of the eyepiece increases, the image loses its detail and clarity. If you want to achieve double magnification, then use the Barlow lens in addition to the main eyepiece.
Step 7: Adjust the focus
Once you have set up the telescope and found the object to observe, you need to adjust the telescope focus. To do this, use the focus knob to make the subject look as clear as possible. If it happens that nothing is visible in the eyepiece, then you need to re-align the telescope. This can happen when you use a reflector telescope. To correct the situation, you need to align the primary and secondary mirrors.
You can also use the left and right buttons on the manual controller to focus on the subject yourself. Aim the finderscope so you can see the object at the center of the crosshairs, then use the focus knob. Be careful, as unnecessary movements can cause you to lose focus.
Step 8: Enjoy the view
The last step is the easiest and most enjoyable of all. Once you have completed all the previous steps, finding and focusing on the object of observation, you can enjoy observing the star or planet. You can view all the details by replacing the eyepiece if you need to increase the magnification of the image. The main thing is to practice. Over time this process will become easier and faster for you.
FAQ on Pointing a Telescope
How to aim a telescope at the sun?
A telescope should never be pointed at the sun without a proper solar filter attached to the front of the telescope. Without a filter, the intense sunlight will damage the telescope’s optics.
How to aim a telescope at Jupiter?
There are a few things you need to do in order to aim a telescope at Jupiter. First, you need to find Jupiter in the night sky. You can do this by using a star chart or an app like Sky Guide. Once you’ve found Jupiter, center it in the eyepiece of your telescope. Then, use the finder scope or another sighting device to keep Jupiter centered in the eyepiece. Finally, adjust the focus until the image is clear.
Why can’t I see anything through my telescope?
Most of all, you can’t see anything because your finder isn’t aligned with the telescope. Try to practice aiming during the day using a road sign or a tree nearby. Look through the finder and center it on the target, using the eyepiece with the lowest power.
Where should I point my telescope?
It depends on what object you want to observe. If those are stars or planets that are visible to the naked eye, you can manually point your telescope in the right direction. And if these are invisible objects to the eye, you need to use special maps.
How do you point a telescope to the moon?
The moon is a very easy target that can always be found in the sky, even without a telescope. Move the tube of your telescope toward the moon without using any additional optical means. Center the Moon on your finder. Then move to the eyepiece, using the lowest power.
Using an equatorial mount telescope, align the north-south rotational axis of the mount to be parallel with the Earth’s axis. Find Polaris, the North Star, and rotate the telescope’s east-west axis until it is pointing at the star. Adjust the latitude adjustment screws on the mount until the counterweight is level with the tripod, then tighten the screws. With the telescope pointed at Polaris, turn the knob on the right ascension axis until the needle is lined up with the zero mark. Find the Moon in the telescope’s field of view, and use the knob on the right ascension axis to center the Moon in the eyepiece.
The Best Stargazing View in Eight Steps
A telescope is a rather complex device that requires time and practice to learn how to use. Aiming can sometimes be quite a confusing process. However, it is important to do everything consistently. You need to determine exactly what, where, and when you want to observe. Before aiming the telescope, make sure that the finder and mirrors are aligned. By following all the steps, you will get exactly the desired result and will be able to enjoy the view.
