What is focal length AstroMaster 130?

Designed for near and deep-sky observation with a fast focal ratio for astrophotography/imaging, Celestron’s AstroMaster 130EQ 130mm f/5 Reflector Telescope features a 650mm focal length and an oversized parabolic mirror that produce detailed images of the Moon, clear views of the planets, and the ability to resolve ….

How much magnification is 130mm telescope?

The “maximum” magnification is just a number, usually around 60 times the aperture [in inches]. In this case: 130 mm / 25.4 mm per inch = 5.12 times 60 = 307x magnification.

What eyepiece is best for Saturn?

It is said that any small telescope is capable of viewing Saturn’s rings at 25X magnification. I suggest using a 15mm eyepiece through a Dobsonian telescope (here is the one I own and recommend) for the best chances of success.

What can a 130 mm telescope see?

With a 130mm (5. 1″) aperture size, the Polaris 130 will deliver bright, clear images for the aspiring astronomer to enjoy. Whether you’re viewing the Moon, planets, or deep-sky objects such as nebulae, galaxies, and star clusters, the view through the Polaris 130 will keep you looking up for a long time.

What is a good focal length for a telescope?

A shorter focal length telescope will be more suited to wide field views of the stars. A good all round first telescope should have a focal length of around 1000mm to 1200mm. All refracting telescopes use a glass lens as their primary focusing unit.

How much magnification do you need to see Jupiter?

To look at planets like Jupiter and Saturn, you will need a magnification of about 180; with that you should be able to see the planets and their moons. If you want to look at the planet alone with higher resolution, you will need a magnification of about 380.

Can you see Neptune with a telescope?

So Neptune is not faint by telescopic standards. In fact, it’s bright enough to stimulate color vision through any telescope with 4 inches (100 mm) of aperture. Look for a hue quite similar to Uranus’s, though somewhat bluer. Close-up of chart showing Neptune’s path on the sky in 2021-2022.

Can I see Saturn rings with 70mm telescope?

The colorful bands and belts of Jupiter, as well as its four major moons, and the rings of Saturn are clearly visible in a 70mm telescope.

What focal length do you need to see planets? A telescope with a long focal length (1000mm+) is required for a detailed photo of the planets. The photo below features my best planetary images of Jupiter, Saturn, and Mars using this method.

What can you see with a 4mm eyepiece?

The Apertura 4mm Plossl eyepiece produces sharp, high magnification views of the Moon and planets, and, depending on the telescope, will also work great for double stars, planetary nebulae, and other deep sky objects. Like most Plossl eyepieces, the High Point 4mm has a 52º apparent field of view.

What can I see with a 130mm Newtonian telescope?

It is definitely possible to see galaxies and nebulas. For the closer galaxies like Andromeda, you might be able to see how the light concentrates at its core and its disk shape. With a telescope of this power, you can get started with astrophotography and get some great results.

Is 10mm or 25mm better for telescope?

The above formula dictates that a telescope eyepiece with a shorter focal length yields a higher magnification than an eyepiece with a longer focal length. For example, a 10mm eyepiece will always provide a higher magnification than a 25mm eyepiece.

How many mm is a good telescope?

Aperture: A Telescope’s Most Important Feature

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.

What focal length eyepiece do you need?

The most common and time-tested rule of thumb suggests not exceeding a magnification of about 50x per inch of aperture of your scope. For a 4″ telescope, for example, you should stick to less than 200x with your shortest focal length eyepiece. Any higher and the view will become unacceptably dim and less sharp.

What can you see with 700mm focal length telescope? With a 70mm telescope, you will easily be able to see every planet in the Solar System. You will also be able to take a great look at the Moon and clearly distinguish most of its recognizable features and craters.

Which telescope lens is stronger 10mm or 20mm? This means that a smaller number on an eyepiece gives a higher magnification. A 10mm eyepiece would provide twice as much magnification as a 20mm eyepiece.

Which Celestron eyepiece is best for viewing planets?

Ultra-short focal length (2-4mm) eyepieces provide very high power magnifications and are best for observing the planets and the moon on shorter focal length telescopes.

What size telescope do I need to see Saturn’s rings?

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.

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

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.

What magnification do I need to see the rings of Saturn?

Saturn’s rings should be visible in even the smallest telescope at a magnification of 25 times. A good 3-inch scope at 50x magnification will show the rings as distinctly separate from the ball of the planet.

What telescope can see Mars?

Any telescope will work for Mars, but the bigger, the better. A 4-inch refractor or a 6-inch reflector are the recommended minimum. Apply high power (175× or more), and wait for a night with steady seeing, when the Martian disc is not blurred by turbulence in our atmosphere.

Can I see galaxies with a telescope?

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 400mm focal length good for telescope?

* 400mm (f/5.7) focal length and 70mm aperture, fully coated optical glass lens, with high transmission coating, can create stunning images and protect your eyes. The perfect telescope for astronomers to explore the stars and moon.

Is longer focal length better? The longer the focal length, the narrower the angle of view and the higher the magnification. The shorter the focal length, the wider the angle of view and the lower the magnification.
