Question: What Telescope Is Best For Deep Space?

Can you use a telescope in the daytime?

It is safe to observe anything during the day, as long as you don’t point the telescope close to the Sun.

Just stay away from the Sun and you’ll be fine.


Mercury is pretty hard to observe at other times than during the day (or dusk), and yet astronomers have been observing it for a very long time..

Is a 70mm telescope good?

However, a 70 mm refractor (which collects 36% more light than a 60mm telescope) is considered by many amateur astronomers to be the minimum size for a good quality beginner refractor telescope. It is acceptable for observing bright objects like lunar details, planets, star clusters, and bright double stars.

Which lens is used in telescope?

This type of telescope is called a refracting telescope. Most refracting telescopes use two main lenses. The largest lens is called the objective lens, and the smaller lens used for viewing is called the eyepiece lens.

How big of a telescope do you need to see galaxies?

If you want to observe galaxies — and I mean really get something out of the time you put in at the eyepiece — you have to use a telescope with an aperture of 8 inches or more. Bode’s Galaxy (M81) glows brightly enough to show up through binoculars, but the larger the telescope you can point at it, the better.

What can I see with a 4 inch telescope?

A four inch refractor telescope will show you all the planets of the solar system, including Pluto, which is technically no longer a planet. It will also show you deep-sky objects such as the Andromeda galaxy and the Crab Nebula, which is the remnant of a supernova explosion.

How can I make my telescope stronger?

Can I see the rings of Saturn with my telescope?

The rings of Saturn should be visible in even the smallest telescope at 25x [magnified by 25 times]. A good 3-inch scope at 50x [magnified by 50 times] can show them as a separate structure detached on all sides from the ball of the planet.

What can you see on the moon with a telescope?

Neophytes to astronomy might initially consider this a come-down, but are then pleasantly surprised the first time they look at sky objects with a pair of binoculars; they can reveal many sights that most folks think require a telescope – including the crescent phase of Venus, the four Galilean satellites of Jupiter, …

What can I see with a 6 inch telescope?

The bigger the aperture the better. With a 6-inch telescope you can discern craters on the Moon as small as about a mile across — half the size of those visible in a 3-inch scope (under the same conditions using the same magnification).

How strong of a telescope do I need?

A useful rule of thumb is that the maximum magnification your telescope can handle is around 50 times the telescope’s aperture in inches. Any higher and the image gets too dim and blurry. So, a 6 inch scope can magnify up to 300x, while an 8 inch scope can magnify 400x.

What planets will be visible in 2020?

Jupiter and Saturn are the planets to watch as darkness falls in August 2020. They are near one another on the sky’s dome, with Saturn following Jupiter westward across the sky from dusk/nightfall until the wee hours of the morning.

How big of a telescope do I need to see the flag on the moon?

around 200 metersThe flag on the moon is 125cm (4 feet) long. You would require a telescope around 200 meters in diameter to see it.

How do you know if a telescope is good?

As a rule of thumb, your telescope should have at least 2.8 inches (70 mm) aperture — and preferably more. Dobsonian telescopes, which are reflectors with a simple mount, provide lots of aperture at relatively low cost. A larger aperture lets you see fainter objects and finer detail than a smaller one can.

What size telescope do I need to see the rings of Saturn?

Viewing Saturn’s Rings The rings of Saturn should be visible in even the smallest telescope at 25x. A good 3-inch scope at 50x can show them as a separate structure detached on all sides from the ball of the planet.

Is buying a telescope worth it?

Most telescopes that cost less than $300 aren’t really worth it. … A telescope’s most important attribute is its size, meaning the diameter of its main mirror or lens. The bigger the telescope, the more light it collects, which allows you to see dimmer objects. A popular first telescope is a Dobsonian.

How do you make a telescope to see planets at home?

To make a simple telescope at home, you will need the following:two magnifying glasses – perhaps 1 – 1.5 inches (2.5-3 cm) diameter (it works best if one is larger than the other)a cardboard tube – paper towel roll or gift-wrapping paper roll (it helps if it is long)duct tape.scissors.More items…

What are the 4 types of telescopes?
