What can an ordinary astronomical telescope see?

If it is an astronomical telescope, you can see the faces of planets, such as Venus, Neptune, Pluto, Jupiter and the profits and losses of some planets' satellites, as well as some galaxies, nebulae and messier objects. The limit magnitude of our naked eye is 6, and we can see darker celestial bodies with astronomical telescopes, which is also related to its caliber. Lines and planes are some of the more chaotic objects that can be seen with astronomical telescopes:

You can find some nebulae visible to the naked eye, such as some messier objects:

The name of the magnitude constellation type

M 8 6.0 Sagittarius diffuse nebula lagoon nebula

M 16 7.0 hydra diffuse nebula skyhawk nebula

M 17 7.0 Sagittarius diffuse nebula swan nebula

M20 9.0 Sagittarius Nebula trifid nebula

M27 7 7.4 Fox Planet Cloud Dumbbell Nebula

M3 1 3.4 Andromeda spiral galaxy Andromeda large galaxy

M33 5.7 triangle spiral galaxy triangle galaxy

M42 4.0 Orion Diffuse Nebula Orion Large Nebula

M5 1 8.4 spiral galaxy, a spiral galaxy in Canis constellation.

M57 4. 1 lyra planetary ring nebula

M63 8.6 Canine Spiral Galaxy Sunflower Galaxy

M64 8.5 Backward spiral galaxy Black-eyed galaxy

..................

There are many. The landlord can look at messier, not only nebulae, but also some cluster galaxies. After finding it, here is a messier objects table arranged in the order of marathon observation. M45、M42、M43、M4 1、M35、M3 1、M32、M 10、M77、M33、M79、M74、M76、M52、M 103、M34、M38、M36、M37、M 1、M78、M50、M47、M46、M93、M48、M44、M67、m 8658

You can try it sometime.

I hope it helps you.
