What's the fun of playing astronomy? I bought an astronomical telescope and thought it was nothing. I just need to look at the stars with the naked eye.

To play astronomy, you must first make clear what you can see according to your knowledge level and financial resources (generally fun, such as the moon crater, sunspot, M3 1, M42, which are relatively large messier objects, Venus, Jupiter, Saturn and Mars), and then make a better all-day star map, in a place far away from urban light and with good atmospheric conditions (the higher the altitude, the better the sunny. The farther away from the city, the better) familiarize yourself with the constellations you can see in your geographical position with your naked eyes or with binoculars. All astronomy enthusiasts start with binoculars. First of all, we should know the constellations and directions in the sky and some basic targets, such as M3 1 Andromeda Nebula and Pleiades Cluster, which can be observed with naked eyes when the weather is fine.

Then you can buy an astronomical telescope. The higher the magnification, the better. Generally speaking, it depends on the aperture. The larger the aperture, the higher the resolution. Refractive aperture is generally above 80, which is relatively mainstream. It's no use reducing the magnification, the image will be blurred. If you don't know enough about the orientation and constellation of the starry sky, you won't know where to aim when you get the telescope. Therefore, we must do our homework as mentioned above. Before going out to watch the stars, you must surf the internet or consult magazines (such as astronomy enthusiasts) to understand the main points, such as the real-time position of planets and special astronomical phenomena, so as to know where the telescope will point. Among the planets, Jupiter and Saturn are easy to see. Saturn has a halo. Jupiter can see the big red spot with clouds in my Marca 150/ 1900 mirror, but it all depends on the eyesight, because it is a very small point in the telescope. The gorgeous big pictures we usually see are basically taken when the detector flies over the planet, and our personal equipment can't be compared.

In short, it is suggested that the landlord spend about 200 yuan to buy a large-caliber telescope to learn first. It's better to buy a refracting telescope from the beginning, which is easier to learn. It's better to have a theodolite or a declination meter on the tripod, so that you won't be crazy when using it in idolization. As for my high-precision electric declination meter, it is unnecessary for beginners or people who are not engaged in astrophotography, and the price is not cheap.

However, if you really don't have the patience to study these, just want to see the excitement, such as the lunar crater, or just to follow the fashion, you can buy an astronomical telescope below 200 yuan to play, and you won't feel bad if it breaks down. However, I advise you to make a tunnel. As long as you have time and interest, it is not impulsive. Astronomical observation is not so far away for ordinary people. I believe you will become a great person in a few days ~

I wish you a smooth journey in astronomy, and the infinite charm of the stars in the night sky is waiting for you!
