"Of the billions and billions of stars in the heavens, only about 6,000 can be seen from the earth without a telescope. And about a quarter of these 6,000 stars cannot be seen from most lands north of the equator."
Other estimates range anywhere from 2000 to 10,000, depending on where you are and what reference you use.
The question needs tighter limits. Where are you on earth? Do you have foggy coastal air, dirty city air with lights, or a dark mountain top or clear desert air? What size telescope do you mean? A two inch spyglass or the 60 inch on Mt Wilson? Even larger scopes are not used visually, but only with instruments. How young are your eyes, what is the maximum pupil opening when dark-adapted, and do you have good night vision? With just average eyes with no problems or visual aids, and in perfect viewing conditions, one can see several thousand stars in the entire sphere of the sky. Since a person on earth can see less than half the sky at one time, it may be just over a thousand at any one time. Telescopes add much light to the view. With an eight inch diameter reflector, one could see more than a million stars. With a twelve inch one, perhaps three to ten millions. The Milky Way galaxy has billions of stars, but we can see only the small part nearest us. Most of it is behind vast clouds of dust and gases. And other galaxies are too far away for most small telescopes to pick out individual stars. Best guess is anywhere between a few hundred thousand to a few billion stars, but it is not possible to narrow that range without more limits to the question.
Under optimum conditions, on certain nights, far from any city lights, you can see a total of about 3.500 stars with the naked eye (and 2,500 is more typical). With 10X50 binoculars, you can see 125,000. With an observatory telescope many billions more than that.
You can literally see millions of stars on a very clear night without a telescope. The best views are taken from unlit places like the forest.
Without a telescope, you can see about 6,000 stars in the night sky.
Between one and 373.2 millions.
about 6000
Definitely, a 500-mm (20-inch) telescope is a large instrument because 500 mm is the diameter of the main mirror or lens, so the telescope would be 3-5 metres long. A telescope this size could see faint stars down to a magnitude of round about 15. Remember that you don't need any telescope at all to see stars. On a clear night in a dark place, you can see a few thousand of them with only your eyes.
Uranus is in our galaxy, the Milky Way. Everything you can see in the sky at night without a telescope, all the planets and stars are all in our galaxy.
You can see the faint edge of the Milky Way, our galaxy. It is not a sharp edge, but appears as an indistinct band across the night sky. That is how it got its name. The cloudy appearance of the Milky Way is actually the effect of the billions of stars that are gathered near each other in our disc-like galaxy.
Galileo discovered stars by using the telescope?
Did you ever think you had to clean the lens you look through on the telescope. If your not looking through the telescope may be you have a problem with your eye or you are glazing at the stars which can make the appearance blurry.
No. All the stars you see at night are in our galaxy. Stars in other galaxies are much too far away to be seen without a powerful telescope.
It may surprise you to know that only about 6,000 stars can be seen without a telescope at any one time in the night sky.
Meteors (two to three an hour on a typical clear night), comets on occasion, and if you have a good telescope, other galaxies and the occasional planetary nebula.

The night time stars are suns, so distant they appear as points of light. Note that the planets Mercury, Venus, Mars, Jupiter, and Saturn can be seen without a telescope and can be mistaken for stars.

some stars.
Yes, it is possible today.====================================There are billions of galaxies, and you haven't mentioned which one you'reinterested in.If you mean the Milky Way galaxy ... the one of which the Sun is a member ...then the task is easily begun without any telescope at all.ALL of the stars you see with your eyes when you stand in your back yardand browse the night-time sky are stars in the Milky Way galaxy.Spotting individual stars in OTHER galaxies does require a telescope.
Interference from Earth's atmosphere.
look in the sky at night. The clearer the sky the more stars you see. Go to the country side and in a clear night there are lots and lots of stars!
On a clear night, you can see ca. 3000 stars at once, with the naked eye. For fainter stars, you need a binocular, or telescope.
