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..
Is a 70mm telescope good?
A 70mm telescope is a great starting point for beginners as well as more intermediate astronomers. You can have a decent view of almost all of the prominent objects in the night sky seen from the earth.
What lens should I use to see Jupiter?
In most cases you need two to three eyepieces of different powers, say a 25mm, 15mm and a 10mm and a barlow lens. A 2X barlow will double the power of an eyepiece practically turning a 25mm into a 12.5mm. If you have any filters, an 80A Blue seems to work fairly decent on Jupiter.
How far away is the closest galaxy to ours?
Distance Information The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.
What can you see with a telescope during the day?
Image via Rima Biswas in Baltimore, Maryland, December 2016.The sun. Obviously, you can see the sun during the day, but paradoxically, we’re told not to look, for fear of harming our eyes. … The moon. … The planet Venus. … Earth-orbiting satellites. … The planet Jupiter. … The planet Mars. … Stars during eclipses. … Daytime comets.More items…•
How big of a telescope do you need to see planets?
Five of the Best Telescopes to See Planets Celestron 21037 PowerSeeker 70EQ. Orion AstroView 90mm Refractor. Celestron NexStar 4 SE Maksutov-Cassegrain. Sky-Watcher ProED 100mm Doublet APO Refractor (tube only)
Can you see other galaxies with a telescope?
Answer: Yes, you can see a few other galaxies without using a telescope! … The nearby Andromeda Galaxy, also called M31, is bright enough to be seen by the naked eye on dark, moonless nights. The Andromeda Galaxy is the only other (besides the Milky Way) spiral galaxy we can see with the naked eye.
What 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.
How much magnification do you need to see Jupiter?
Great seeing conditions and a very dark night are must-haves. After that, you’ll need to make use of at least 100x magnification and probably >150x to have a chance of seeing it. The very best opportunities come when Jupiter is at opposition because it is closer, giving a much larger target for us to see.
What magnification do you need to see Venus?
50XEven a small telescope, say 60 mm in aperture, can show you Venus and allow you to see it go through its phases. I would recommend using a magnification of 50X or higher while observing venus using a telescope.
What is the 500 rule in photography?
To achieve points of light you can use a simple rule that’s often called the “500 Rule”. For example; let’s say you’re taking a shot with a 24mm lens on a full frame camera. 500 / 24 = 21 seconds, which you can round to 20 seconds.
Can you see Venus with a telescope?
Although any telescope (or steadily-held binoculars) will allow the phases of Venus to be seen, the planet is a notoriously difficult one to observe, for three main reasons. … Thirdly, the planet itself is permanently cloaked in thick cloud, so its surface features are never visible through telescopes.
What can you see with a 20 mm telescope?
All telescopes have a fixed focal length, just like lenses on a camera. So a 20mm focal length will give you a wider field of view than say a 300mm. You will also notice that with a 300mm you get a larger image of the subject, be it a person or animal or even the moon.
What is the best type of telescope for astrophotography?
apochromatic refractorMost experienced astrophotographers find that a good 4 or 5 inch apochromatic refractor is an excellent choice for deep-sky astrophotography because of its versatility. Such a scope can keep you busy for a long time and last a lifetime. For beginners, a small 65mm, 70mm or 80mm refractor is an excellent choice.
What planets will be visible in 2020?
Jupiter and Saturn are the planets to watch as darkness falls in September 2020. They are near one another on the sky’s dome, with Saturn following Jupiter westward across the sky from dusk/nightfall until well after midnight.
What is a good telescope for beginners?
The Celestron Astro Fi telescopes do away with all that stuff, because you already own it! Your Apple or Android smartphone or tablet makes a perfectly excellent telescope controller. All you need to do is download Celestron’s free SkyPortal app from the Apple App Store or Google Play.
Can you see Milky Way with bare eyes?
More than 100,000 light years in diameter, with more than 100 billion stars and at least as many planets, the Milky Way is arguably the most impressive feature of the night sky that you can see with the naked eye.
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 strong of a telescope do I need?
As a rule of thumb, your telescope should have at least 2.8 inches (70 mm) aperture — and preferably more. … For most purposes, a telescope’s maximum useful magnification is 50 times its aperture in inches (or twice its aperture in millimeters) . So you’d need a 12-inch-wide scope to get a decent image at 600×.
