The difference between the astronomical telescope and a regular telescope
An astronomical telescope is also a telescope, and the basic structure of a telescope is similar. (There are two types of telescopes: Galilean and Kepler. Galilean consists of a concave lens and a convex lens, while Keplerian consists of two or two sets of convex lenses. Galileo’s positive image, Kepler’s inverted image) but the telescope has a larger aperture and better optical performance. Now let’s learn the difference between the astronomical telescope and a regular telescope.
The difference between astronomical telescopes and ordinary telescopes
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.
Is an astronomical telescope and refracting telescope the same?
A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope). The refracting telescope design was originally used in spyglasses and astronomical telescopes but is also used for long-focus camera lenses.
Which is a better telescope reflector or refractor?
If you are interested in astrophotography, purchasing a refractor is a better option because of it’s specialized optic design that captures deep space objects like galaxies and nebulae. If you are interested in brighter celestial objects like the Moon or planets or a beginner, a reflector telescope is ideal.
Can you see planets with a refractor telescope?
Generally speaking, the best refractors for seeing planets will give a better view per mm of aperture than a reflector. They are so much better for viewing planets as the detail they bring out at higher magnification is not subject to chromatic aberrations.
