Anonymous users2024-02-05I don't agree with what the upstairs says.
For a telescope, the larger the aperture is indeed the better, and the aperture determines the telescope's light-gathering capacity and resolution. It is the most important parameter of the telescope, but the ** of the telescope is also proportional to the cubic of the aperture, and the large aperture also means the rapid increase of the **.
As for the eyepiece upstairs said to be small (it should be the focal length) and the focal ratio is large, that is to improve the magnification.
The focal ratio (focal length aperture) of the telescope is relatively long and suitable for observing planets, and relatively small for finding deep-sky objects.
The eyepiece of the telescope has a lot of exquisiteness, a good eyepiece should be composed of three glass lenses, which can eliminate chromatic aberration and spherical aberration under a relatively high magnification, but the landlord gave only two eyepieces in the accessories H4 and H20, if there are only these two eyepieces, H4 will definitely be shelved by me, because the magnification is too large. In the process of using the telescope, I also hope that the magnification of the telescope is as small as possible, so that it is easier to find celestial objects and the image quality is not easily affected.
As for the landlord's telescope, which is a popular telescope, it is still okay as the first telescope to start. I have not used the brand of Xinglunte, but it is very hot at these times, and most of the telescopes recommended by netizens will know that this brand is recommended, I have not used this brand, so it is inconvenient to say more. But in the low-end telescope, I personally admire Boguan.
As for these popular telescopes, it is recommended that the landlord choose the Phoenix, after all, it is cheaper.
But I want to remind the landlord that the stars in the sky are not just a telescope to point to find, deep sky objects to find is to rely on a good basic skills, this is not easier than finding a grain of sand from the desert, a few days ago when I went out to observe the meteor shower by the way to find some deep sky objects, Aquarius M2 took me an hour, M2 in the brightness of deep sky objects steadily ranked in the top 30, but for me like a person who is more than less than the top (after all, looking for M31 in the back, M45,M42These old friends have been killed in seconds.,M34 that I've never looked for can also be done in 5 minutes.,It's probably not appropriate to say that I'm a complete newbie). Give an example of your own example to the landlord as a warning.
Personally, I suggest when the landlord can recognize the 30 constellations in the sky, and can familiarly point out the location of the five planets when to buy a telescope, at that time the naked eye alone may not be full, at this time into the telescope is better than now.

Beijing Galaxy Telescope will answer for you:
At present, the domestic binoculars are relatively good, especially the binoculars, the series and models are more, and the reputation is also good. >>>More
Beijing Galaxy Telescope Answer:
The gap between astronomical telescopes is very large, and our ordinary junior astronomy enthusiasts can choose non-professional mirrors (professional mirrors are very expensive, and they are generally used for professional observation). **In the 1000-2000 yuan or so low-end astronomical telescope can be, of course, if you are very passionate about astronomy, for the observation effect of high requirements, you must choose the high-end telescope, refraction and reflection have their own advantages and disadvantages, mainly depending on what you want to observe, choose the best one for yourself; >>>More
Personally, I recommend buying a large-caliber double-barrel, if the budget is relatively rich, you can consider 15*70 or 20*80 racks on the tripod, it will feel very good, more affordable large-caliber double-barrels can consider the 20*80 of the wolf, 15*70 can consider Boguan, but Boguan's ** is more expensive than the above two brands. If the budget is tight, you can consider 7 * 50 or 8 * 42, these two types of telescopes can be handheld without the need to go on a tripod, you can consider pandas, sky wolves and Boguan, ** almost 300-500 is enough. Note that it is best to purchase the Panda Telescope from its manufacturer or check with your local distributor.

It's not bad, but I'm going to tell you: the telescope is not the larger the magnification, the better, for some unprofessional telescopes, sometimes the magnification is not good, that is to say, there will be blurry in the distance, if you want to buy a little more professional, it is best to choose some waterproof and anti-falling. I think it's better to return the iris (some of the people on the market say that the iris can have night vision, but in fact, it is a deception to consumers, and the level of night vision is often more than 1,000 yuan!) >>>More
