I really envy having such an astronomical telescope, and I can see a lot.

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.
