Know about astronomical telescopes!

If the landlord has not touched the telescope, please don't expect too much from it. A telescope within 2000 yuan can see the planets in the solar system, but the effect you see is only a little bigger than that seen by the naked eye. Looking at Jupiter is just a big bright spot and a few small bright spots next to it. Looking at the nebula is far from those photos on the internet, just seeing a nest of bright spots.

Bought an astronomical mirror, 1760 yuan. After reading it several times, I lost interest. There is no use except watching MM now.
