    Summary. Hello! When choosing a good astronomical telescope, there are several factors to consider:

    1.Penetration: How much light an astronomical telescope can collect is crucial, so it is more effective to choose a larger aperture telescope.

    2.Measurement performance: such as the resolution and stability of the telescope, these characteristics also affect its observation ability.

    3.Accessories: In addition to the telescope itself, it also needs to be equipped with some auxiliary accessories, such as cameras, sights, etc., only the right accessories can achieve the best observation effect.

    4.Cost: According to the actual needs, we can choose a more suitable equipment, and consider factors such as budget while taking into account performance.

    Hello! To choose a good astronomical telescope, you need to consider the following factors:1

    Penetration: How much light an astronomical telescope can collect is crucial, so choosing a larger aperture telescope is more respectful. 2.

    Measurement performance: such as the resolution and stability of the telescope, these characteristics also affect its observation ability. 3.

    Accessories: In addition to the telescope itself, it also needs to be equipped with some auxiliary accessories, such as cameras, sights, etc., only the right accessories can achieve the best observation effect. 4.

    Cost: According to the actual needs, you can choose the most suitable equipment for collapse, and consider factors such as budget while taking into account performance.

    In addition: 1. First of all, look at the model, for beginners, mainly look at the focal length and caliber of the Sen, the larger the focal length and caliber, the better, and the more expensive. 2. The magnification of astronomical telescopes mainly depends on two focal lengths, namely the objective focal length and the eyepiece focal length.

    The focal length of the objective lens is constant, but the eyepiece can be flexibly combined. 3. When purchasing, look for the brand. The astronomical telescope is finely made, with many models to choose from, and is cost-effective, suitable for astronomy enthusiasts.

    4. Sirius Astronomical Telescope, **cheap, suitable for beginners in astronomy. 5. If you are an audiophile, you can choose the American Doctoral Energy Astronomical Telescope, which is powerful and designed for enthusiasts.

    Finally, 1. Determine aperture and focal length: Aperture is the most important parameter of astronomical telescopes, and the size of the liquid diameter directly determines the resolution of imaging. The focal length is the distance from the principal point of the telescope's optical system to the principal focus.

    Magnification is obtained by dividing the primary lens focal length by the eyepiece focal length. Divide the focal length of the telescope by the aperture to obtain the focal ratio, which reflects the telescope's light-carrying capacity, and the smaller the value, the better. 2. Choose a style:

    There are three types of common astronomical telescopes: refractive, reflective, and reverse. The refractive imaging effect is good, and there is chromatic aberration. The reflective type is small and lightweight, the aperture can be very large, and the imaging has spherical aberration.

    The catadioptric type has a refractive correction mirror in front of the reflector, which has the advantages of both the refractive pure emission type and the reflection type.

    Determine which astronomical telescope you need: Common astronomical telescopes are divided into refractive, reflective, and refractory. The refractive imaging effect is good, the reflective type is small in size, and the refractive type has a refractive correction mirror in front of the reflector, which has the advantages of both refractive and reflective type.

    Determine the aperture of the telescope to buy: Aperture is the most important parameter of an astronomical telescope, and the size of the aperture directly determines the resolution of the imaging. Other Accessories:

    The tracking equipment includes an equatorial mount and a level, and the equatorial mount is manually adjusted for observation. It is recommended to choose stainless steel for the tripod, which is more stable when fine-tuning. <

    Dear, for you to find out how to buy astronomical telescopes.

    1. I bought it for astronomy popularization, and accompanied my children's family and friends to occasionally look at the starry sky. In this category, it is enough to spend less than 1,000 yuan, and it usually does not take up space at home, and when you go out, you can take it everywhere with a hand-held suitcase. 2. Conduct introductory observations of astronomical knowledge.

    This category costs 1,000 to 5,000 sufficiently. The telescope is a bit big, and you need a place to put it at home and a car to pull it out. 3. Engage in astrophotography and professional observation.

    This kind starts from five or six thousand, and goes up to hundreds of thousands. This requires a yard at home, a sundeck, etc., and special boxes and vehicles are needed to pull it when you go out.

    Dear, hello, I am glad to answer for you: how to choose an astronomical telescope? A:

    1.Determine the local weather conditions in a year, the number of observable days is two weeks per month, and the city's light pollution is not serious, and then consider whether to buy an astronomical telescope. 2.

    It depends on the economic strength in hand, and consider it comprehensively. 3.There are two kinds of telescopes, direct and reflective, the direct observation of a single star is the best, the requirements for the lens are not particularly high, and the volume is long; Reflective observation of a sky area is best and has a short volume, but there is a concave mirror inside that needs to be coated regularly, otherwise the image will not be clear.

    4.The clarity of the telescope is related to the diameter of the objective lens, the larger the objective lens, the clearer the image, so it is advisable to choose a larger diameter, and it is recommended that the diameter of more than 200mm (** will be more expensive) 5Comprehensive suggestion, ** in more than 5,000, objective lens more than 150, direct type, base frame to choose a little better.

    Don't be obsessed with magnification, as long as it's astronomical. If you have a mine at home, you can consider an objective lens of about 300, which is estimated to be about 2 30,000 professional grade. I hope mine can help you, I wish you a happy life, if mine is helpful to you please give me a 5 star praise Oh, thank you for your support to me.

Friend, after reading the ** you sent, I can tell you that the effect of these pictures is not reached, and it is not enough to see only a small bright spot, but it is almost, you can still vaguely see that there are two small edges and corners next to the stars, which is a graphic halo, but it is impossible to distinguish that it is a ring, such a telescope can only be used for sightseeing, at most you can see the lunar crater, if your main purpose is astronomical observation, such a telescope you will regret when you buy it!

It's not high, if it weren't for his automatic star search, it would be equivalent to a telescope of 500 yuan. Automatic star hunting isn't very useful, unless you're the kind of enthusiast who uses tens of thousands of dollars of equipment to shoot galaxies and nebulae all night. Every time you go downstairs for astronomical observation, holding a telescope for automatic star searching, you need to spend dozens of minutes to enter the time, enter the coordinates, align the north, horizontal placement, N star calibration and other complicated steps, in order to automatically find the star, and this low-end automatic star search theodolite accuracy is often very low, sometimes the automatic star search is not accurate. >>>More
