F900114 Astronomical Telescope
Phenix F900114 Professional 90X Outdoor Traveling Equatorial Tripod Reflector Astronomical Telescope for viewing Star Moon
An astronomical telescope is an instrument that works on the principle of optics used to view the enlarged image of heavenly bodies like stars and galaxies. The end image formed by an astronomical telescope is always virtual, inverted, and magnified. It is an excellent means for analyzing and collecting radiation from heavenly bodies situated far from the universe we live in. It helps scientists to observe subjects with a detailed view even if they are at an infinitely large distance.
An astronomical telescope's construction consists of two convex lenses: An objective lens placed at the position O and an eyepiece placed at the position of E. The focal length of the astronomical telescope is fO, and the eyepiece's focal length is fE. The aperture of the objective lens is taken large as compared to the eyepiece so that more light can be received by it from distant objects and a brighter image can be formed.
Benefits of F70060 Astronomical Telescope
Magnification
When you look at the landscape or the moon through an astronomical telescope, objects seem to get closer. At the same time, you can also see many holes on the surface of the moon. This is because the telescope has the function of magnification.
Eyepiece focal length
In magnification calculation, the focal length of the objective lens is usually fixed, and different eyepieces can be used to observe the star seasons with a variety of magnification. The larger the magnification, the smaller the view.
Light collecting power
Another important feature of a telescope is light collecting power. Light collecting power is the ability of a telescope to collect light. The amount of concentrating power depends on the diameter of the telescope, the bigger the diameter, the darker the stars can be seen.
Objective lens
The larger the diameter of the objective lens, the darker the magnitude can be seen. The smaller the diameter of the objective lens is suitable for observing planets. For different stars, different telescopes should be used.
Type of F70060 Astronomical Telescope
Ground based telescope
A ground-based telescope is a telescope on the ground. At present, all optical telescopes in China are ground-based telescopes.
Space telescope
A space telescope is a telescope placed in space. Being separated from the atmosphere, the observation effect will not be affected by the atmosphere. There is no water vapor, dust, etc. that will affect the clarity. There is no air turbulence, and the shooting quality is high. There is no day and night change, so you can shoot all day, and the shooting time is long. But there is a fatal flaw, that is, the price is too high, and its price can reach hundreds of times of an ordinary professional astronomical telescope.
Refracting telescope
The lens is a convex lens and a concave lens. When the object is beyond twice the focal length of the first lens, the light passes through the first lens and becomes a reduced real image point, and the image point is within one time of the focal length of the second lens.
Kepler telescope
The lens is two convex lenses. The object is beyond twice the focal length of the first lens. The light passes through the first lens and becomes a reduced real image point. The image point is within one time the focal length of the second lens. The light continues to diverge after passing through the image point and passes through the second lens to form a magnified and inverted virtual image. reaches the human eye. In actual operation, a prism is used to make the inverted image upright.
Reflecting telescope
Reflecting telescopes mainly use a parabolic reflector as the primary mirror, and the focus of the telescope is located in front of the primary mirror. After many failures in grinding lenses, Newton decided to use a reflector instead of a lens as the primary mirror, and used a plane mirror to guide light out of the barrel from the side, thus inventing the Newtonian reflecting telescope.
1. Different multiples and uses
Multiple The multiple of the different ordinary telescope is about eight to fifteen times, suitable for observing nearby targets, ordinary telescope compact structure, small and portable, can be carried in travel, can also be used for concerts, sports events, and other occasions. Astronomical telescopes have large multiples, most of which can be 50 to 100 times, or even more than 200 times, and are mainly used to observe celestial bodies, but occasionally low-power eyepieces can be used to observe ground targets. The complex structure and large size of an astronomical telescope make it difficult to take with you when traveling.
2. Look different
An astronomical telescope usually has two mirrors. The larger one is the primary mirror, which is used to observe the target. The smaller one is called the star finder, which is used to find the target, also called the sight scope. An ordinary telescope consists of two tubes of equal size.
3. Structure and difference
Although an ordinary telescope is small, the sparrow is small, the necessary parts are highly integrated, some products are completely sealed inside, waterproof, dustproof function. The common telescope has a double barrel and single barrel of a cent, the product on the market is in the majority with a double-barrel. Optical principle only "refraction" a kind, but its prism structure has Paul type and roof ridge type points.
There are many parts of the telescope and all of them can be detachable. The inner part of the telescope is not sealed, so it can not be used in high humidity or dust weather, otherwise, water vapor and dust will enter the inner part of the telescope and affect its use. In terms of structure, astronomical telescopes are single-barrel designs and need to be connected to a tripod when used.
4. The distances of observed objects vary
Telescopes can observe stars beyond the earth. Ordinary telescopes can only look at slightly closer objects.
5. Different uses
Telescopes are mainly used to observe astronomical changes. Ordinary telescopes are usually used only to observe objects on the ground.
6. The optics are different
In terms of optical principle, to achieve a longer observation distance and better imaging effect, the optical structure of astronomical telescope is unrestrained, including refraction type, reflection type, and refraction reflection type. The picture direction needs to be changed by a positive zenithal mirror or positive eyepieces.
Astronomical telescopes are specially designed for viewing the sky. Many important indicators for viewing effect are ignored in the design of astronomical telescopes. The viewing effect of the same grade of astronomical telescopes is far less good than that of ordinary desktop telescopes (such as field of view, edge clarity, color reduction, etc.). For non-astronomy enthusiasts, desktop telescopes are more versatile and have better overall results than astronomy.
1. Preparation work: Determine the observation location, time and weather conditions, ensure that the weather is clear, cloudless or with few clouds, and use appropriate magnification based on the stability of the astronomical telescope.
2. During the day, aim the main lens tube at a distant target, such as a tall building in the distance, a mountain in the distance, etc., and install a low-magnification eyepiece, such as 20mm. After roughly aligning the lens barrel with the target, adjust the focus. Continue until the target is clearly visible and centered on the primary mirror.
3. Adjust the position of the telescope: Place the tripod of the astronomical telescope on a stable ground, then point the telescope toward the sky, and use the azimuth and height adjustment knobs to adjust the field of view until you find the celestial object you want to observe.
4. Focus adjustment: After pointing the telescope at the celestial object, adjust the focus of the telescope so that the celestial object can be clearly displayed in the field of view of the telescope.
5. Adjust the telescope magnification: Astronomical telescopes usually have different magnifications, which can be changed by changing the eyepiece or adding a magnifying glass. Choose the appropriate magnification based on the size and brightness of the celestial object.
6. Observation: Once you have adjusted your telescope, you can start observing celestial objects. When observing, be careful not to observe for too long, otherwise it may cause damage to the telescope lens.
7. End the observation: After the observation, turn off the telescope and clean it up. At the same time, place the telescope in a dry, cool place to avoid damage.
What Should You Pay Attention to When Using an Astronomical Telescope?
The vast universe has always been a mysterious existence, and people's exploration of it has never stopped. The birth of astronomical telescopes has also helped many astronomy enthusiasts discover more unknown areas of the universe. Therefore, as an astronomy enthusiast, almost everyone has an astronomical telescope, but what issues should be paid attention to when using an astronomical telescope?
1. After installing the astronomical telescope, remember to organize the large and small boxes and place them far away from the telescope, otherwise it will be inconvenient to move around the mirror.
2. Before connecting the main mirror of the astronomical telescope to the equatorial mount, ensure that the right ascension and declination axes of the equatorial mount are locked. When the right ascension and declination are locked, the lens barrel cannot be rotated and can only be adjusted slightly.
3. Before connecting the main mirror of the astronomical telescope to the equatorial mount, carefully check whether the connecting parts between the equatorial mount and the tripod are intact and stable. Avoid damage to the telescope due to sudden breakage of the connecting parts between the equatorial mount and the tripod. Pay attention to the order of installation and removal of the weight and lens barrel.
4. Before connecting the main mirror of the astronomical telescope to the equatorial mount, carefully check whether the connecting parts of the telescope hoop and the connecting plate are intact and stable. Avoid damage to the telescope due to sudden breakage of the connecting parts between the hoop and the connecting plate.
5. After connecting the main mirror of the astronomical telescope to the equatorial mount, pay attention to the balance to balance the telescope, equatorial mount and counterweight, reduce the burden on the equatorial mount, and reduce gear wear and tear.
6. When transporting the main mirror of the astronomical telescope, pay attention to handling it with care to avoid strong impact on the telescope from the outside world.
7. Never use the sun filter at the eyepiece end to view the sun. Even metal sun filters that the merchant claims are of better quality should be used with caution or not used! The most reliable and safe light filtering measure is to use a solar filter at the objective lens and take light reduction measures, such as reducing the clear aperture of the telescope.
8. It is absolutely prohibited to use an astronomical telescope to directly view the sun without any filtering and protection measures. You can view the sun through projection or using a solar filter.
