Popular astronomical telescopes available in the market

Popular Astronomical Telescopes Available in the Market Astronomical telescopes have been popular for a very long time. While earlier only a select few had access to them, today almost anyone can buy an astronomical telescope and observe the mysteries of the universe. The type of telescope that you need to buy will depend on your astronomy goals. While someone who into a full time career in the field may want something that is more sophisticated, those who want one for the fun of watching distant stars and galaxies can go in for the more basic models. For those who want to measure distances up to a range of about 25 kilometers can do with a laser range finder too.

One of the most popular varieties that are available these days are the "refractor telescopes". These telescopes are the long and thin ones which are known for their detailed images. You can adjust the contrast and see clear images of the moon and other planets using this type of telescope. One of the major reasons for their popularity is their portability, apart from the fact that they are also pretty affordable, as compared to the more sophisticated models. The refractor telescopes are ideally suited for the city environs, where you can expect some amount of pollution throughout the day.

Another type that is widely popular is the "Newtonian telescope". Also known as reflector telescopes they are used for viewing distant galaxies or groups of stars.

They are known to produce high resolution images of the deep skies. They are usually used by experts in the field of astronomy. They are also more fragile, as compared to the refractor telescopes and need to be maintained properly for optimal performance. They cannot be used for terrestrial viewing, for you can only see upside down images if you try to do so.

One more type of telescope that is popular is the "Compound telescope". They are also known as Catadioptrics. They are known for their large apertures. They are also characterized by the compact sized tubes. They are considered the most versatile telescopes and are ideally suited for viewing the moon and other distant stars. They are usually very popular with research scholars who use these telescopes away from the crowded urban areas. Another reason for their rising popularity is the fact that they can be controlled using a computer.

While these are the various types of astronomical telescopes available, if you want a device to measure distances terrestrially, then you can go

in for a laser range finder. These days there are powerful laser range finder models available which can help you measure distances up to 25 km with precision. These devices are hand-held, look just like binoculars and as their name suggests, use a laser beam for determining the distance to a particular object.

Whether it is viewing distant galaxies or measuring distance terrestrially, there are several types of sophisticated devices available nowadays.

Based on your requirements, you can go in for a laser range finder or an astronomical telescope.

Chongqing DCHCoast Manufactures Variety of Advanced Optical Instruments Chongqing DCHCoast is a Chinese import and export company involved in manufacturing various advanced optical instruments such as astronomical telescope, binocular, laser range finder, etc.

Optics is a vast branch of physics and is also one of the most developed fields of study. The invention of telescope by Galileo Galilee was one of the earliest major inventions made in the field. Research & development in the field continue to date.

Companies like Chongqing DCHCoast Import & Export Ltd. have played significant role in it by producing variety of instruments such as laser diode module, laser diode, rifle scope tube, night vision goggle, astronomical telescope, monocular, binocular, laser rangefinder, etc. The company has strong portfolio of products as it produces a number models in each category.

DCHCoast has worked closely with original design manufacturers (ODM) and original equipment manufacturers (OEM) partners for years. As a result, the company can provide wide selection of optical and outdoor instruments with excellent service. The design philosophy of the Chinese manufacturer is ‘Green and Lasting’, which ensures that it not only maintains pace with latest technology but also cares for the ecological wellbeing of the Earth. In short, innovative products are manufactured with lesser impact on the natural environment to create an all-round win-win situation for technology and ecology.

Astronomical telescope can be said to be the most advanced of all products manufactured by DCHCoast. It produces both Newtonian Reflector Telescope and Refractor Telescope. Apparently, telescopes are known to all because of the popular depiction of Galileo watching the sky

through one of them. Technically, they are instruments that concentrate and focus light onto a surface to make objects that are far off in the sky visible. Telescopes typically focus visible spectrum of light, i.e., VIBGYOR. There are 3 primary types of telescopes. They are: refractors or dioptrics, which uses lenses; reflectors or catoptrics, which uses mirrors and catadioptrics, which use both mirrors and lenses. Telescopes are used for other purposes besides astronomical observations too.

Similarly, night vision goggles and laser range finders that DCHCoast manufactures also have extensive use in wide range activities. For instance, defence operations that are carried out in deserts or jungles in low light condition at nights are the first thing that comes to mind when night-vision is discussed. Similarly, it assists in spying for good too. DCHCoast has 16 different models of night vision instruments. On the other hand, laser range finders are typically used by personnel in defence, law enforcement and other authorities. They are used for precise calculation of distance to an object. They are based on projection of light beam and its subsequent reflection from the target. However, the advancement in optics has paved way for types of laser range finder. DCHCoast produces 18 different laser range finders.

About DCHCoast Import & Export Co. Ltd. DCHCoast Import & Export Co. Ltd. is based in Chongqing, southwest of China. The company manufactures and sells optical instruments in collaboration global ODM and OEM partners. Its portfolio includes laser range finders, binoculars, astronomical telescope, monocular, spotting scopes, night-vision goggles and laser modules & diodes.

Get Hold of Astronomical and Optical Instruments at DCHCoast The field of astronomy is making advancements. But this advancement would have been a dream, if there were no quality astronomical instruments that aid in the study. Even in the optical field, the world has made a drastic progress. This has been possible due to the new and advanced instruments that are being invented each day. DCHCoast is a company that deals in the manufacture and selling of optical as well as astronomical instruments. The portfolio of products that the company shows is large and includes astronomical telescope, laser rangefinder,

monocular, binocular, laser rangefinder, and others.

Laser rangefinder is an instrument that aids in measurement of the distance for a particular object. It uses the technology of laser for determining the distance. DCHCoast offers various types of laser rangefinders and the commonest of the type is a device that works on the principle of time of flight. The Laser Rangefinder sends a narrow beam of laser pulse to the object and records the time that is taken to be reflected from the object and sent back to the sender. The device in various forms finds its use in varied fields such as military, modeling, forestry, sports, industry production processes, and laser measuring tools.

Binoculars are instruments that magnify the distant objects which are otherwise beyond the sight of naked eye. The binoculars available at DCHCoast consist mostly of the ones that are held in hands. As opposed to monoculars, binoculars offer a three dimensional image of the object. The sizes differ starting from opera glasses to large military models mounted on pedestals. The company sells various kinds of binoculars that include Galilean binoculars and prism binoculars. They sell astronomical binoculars too, which are large and placed on pedestals. The zoom binoculars available from the company are handheld devices which are used to see magnified images of distant objects. The anti-reflexive coats reduce the light loss at each surface. The devices are meant for use in varied fields like range finding, military, and astronomical.

The basic purpose of a telescope is to magnify the distant objects in visible light. DCHCoast offers three different kinds of telescopes that include reflectors that use mirrors, refractors that use lenses, and catadioptric telescopes that make use of mirrors and lenses in combination. The astronomical telescopes available at the company are of two different types that include refractor telescopes and Newtonian reflector telescope. The refractor astronomical telescope makes use of lens for the formation of image. The Newtonian telescope is a kind of reflector telescope that makes use of flat diagonal secondary mirror and concave primary mirror.

The company also sells other optical products.
