A lot will depend on the equipment, location and "how deep" you wish to view and to what clarity.
The Andromeda galaxy is visible for the naked eye under perfect conditions.
The best way is to find out the apparent magnitude of the object you wish to observe. If the value is higher than +7 then it cannot be seen with the naked eye.
If the value is greater than +9.5 then it can't be seen with binoculars.
If the value is greater than +31.5 then even the Hubble Space telescope cannot observe it. (In visible light)
Some visible objects in the sky could be faces and shapes.
As population and population density has grown, the brightness of lights in cities and towns have made it harder to see celestial objects. Generally, you need to travel to areas that provide enough darkness to see many objects in the sky. Going back in time, there was less light in areas of the world.
a same sky but a deep blue
Generally the brightest objects seen in the sky are the moon, some planets, (notably Venus and Jupiter) and stars, Sirius being the brightest.
Charles Messier a French astronomer, published an astronomical catalogue consisting of deep sky objects such as nebulae and star clusters that came to be known as the 103 "Messier objects".It was published in 1774.The purpose of the catalogue was to help astronomical observers, in particular comet hunters such as himself, distinguish between permanent and transient objects in the sky._________________________Interestingly enough, Messier wasn't interested in any of that stuff; Messier was a comet hunter. His catalogue was of "objects that look a little like comets but aren't". His catalogue was designed so that he wouldn't waste time looking at these non-comet objects in his telescope.
Just about any good telescope can be used to see deep sky objects. Of course, the more power a telescope has, the better the viewing will be (compared to a smaller piece of equipment). Shallow sky objects are things like an eclipse, or something "close" to earth (within the solar system). Deep sky objects lie outside our solar system, so using a telescope with a fairly large objective is a perferred choice.
Uranus
They are objects in the sky
Yes pegasus has deep sky objects i am, now doing a report on this particular constellation and i have found at leat 3 one of which is m15 if you look that up on a serch engine you will find it does corrospond with pegasus
No.
The carbon star CW Leo (IRC +10216)
The New General Catalogue (NGC) is a well-known catalogue of deep sky objects in astronomy.
to see what the planets look like. and to see what they would do over time.

Yes, that is often possible. Preferably go to an area without streetlights and watch the sky. You will soon see fast moving shiny objects. These are satellites.
No. Planets do not have comets. They are not related to planets. They are just objects flying through space that we can see in the sky.
