How far can astronomical telescopes see?
In fact, it doesn't make much sense to ask how far an astronomical telescope can see, because all telescopes can see infinity. Even without a telescope, people can see infinity with the naked eye. For example, the moon is 380,000 kilometers away from us and can be seen with the naked eye. The sun is 150 million kilometers away from us and can be seen with the naked eye. M42 is 1,500 light-years away from us and can be seen with the naked eye. It can be seen that the M31 galaxy is 2.3 million light-years away from us and can still be seen with the naked eye, so it is meaningless to ask how far you can see, the key is to be able to see clearly.

If you want to use this telescope well, you have to learn the dimming axis, otherwise the performance will be greatly reduced.
After adjustment, you can see hundreds of lunar craters through this telescope, and can distinguish Jupiter's cloud belts, Saturn's rings, and Venus' circles. If you can find deep sky objects, you can also see some
