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..
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.
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.
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.
Does the Celestron AstroMaster 130EQ have a parabolic mirror?
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
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.
What is a motor drive telescope?
Motor drive automatically tracks celestial objects as they appear to move across the night sky. Download Starry Night Basic Software with a 36,000 object database, printable sky maps and enhanced images including 3D renderings of stars, exoplanets, and galaxies.
What can I see with a 400mm focal length telescope? With 400mm you could watch objects like:
- Andromeda galaxy core.
- Orion nebula, other large emission or reflective nebulae (e.g. Pleiades)
- large star clusters.
- low magnification lunar observations.
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.
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.
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.
How big was Isaac Newton’s telescope?
Isaac Newton Telescope
|The INT dome by moonlight|
|Part of||Isaac Newton Group of Telescopes Roque de los Muchachos Observatory Royal Observatory|
|Telescope style||Cassegrain reflector Newtonian telescope optical telescope|
|Diameter||2.54 m (8 ft 4 in)|
Which telescope is best to see planets?
- Orion GoScope 80 Tabletop.
- Celestron StarSense Explorer LT 114AZ.
- Vaonis Stellina Observation Station & Hybrid Telescope.
- Celestron PowerSeeker 127 EQ.
- Orion StarBlast 6i IntelliScope.
- Encalife SVBONY 501P 70.
- Celestron NexStar Evolution 9.25.
- Sky-Watcher Skymax 127 SynScan AZ GoTo.
What focal length do I want? As a general rule, choose a long focal length lens, like 70, 135, or 200mm to isolate textures and distant features to create dramatic backgrounds. Wide focal length lenses, like 16, 24, or 35mm thrive when you want the entire scene in focus, like when shooting simple landscapes with long leading lines.
How do you know what focal length to use? The lower the focal length number, like 11 or 14 or 24, the more of the scene in front of you gets included in the frame. If you want to fill the frame with a small portion of the scene in front of you, use higher-number focal lengths, like 100, 200 or 400.
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.
How big of a telescope do I need to see Pluto?
First, you need a fairly large telescope, at least 10 inches aperture, because Pluto is currently at magnitude 14.0, very dim in the sky. Second, you need a very good chart of the stars through which Pluto is passing. The best printed star atlases go down to 11th magnitude, which is not faint enough.
How strong of a telescope to see the flag on the Moon?
The flag on the moon is 125cm (4 feet) long. You would require a telescope around 200 meters in diameter to see it. The largest telescope now is the Keck Telescope in Hawaii at 10 meters in diameter. Even the Hubble Space telescope is only 2.4 meters in diameter.
What telescope can I see galaxies with?
High-end pick: Celestron Advanced VX8
You are REALLY going to enjoy this telescope. The Advanced VX 8 is the biggest reflector made by Celestron, one of the most trustable brands when it comes to telescopes. The specifications are perfect for galaxy viewing.
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 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 a 130mm Newtonian? 130mm (5in) to 200mm (8in) or equivalent
b) Stars: double stars separated by about 1 arc second in good seeing, and some faint stars down to magnitude 13 or better. c) Deep Sky Objects: hundreds of star clusters, nebulae, and galaxies (with hints of spiral structure visible in some galaxies).
What focal length is the human eye?
The eye has a nominal focal length of approximately 17mm, but it varies with accommodation. The nature of human binocular vision, which uses two lenses instead of a single one, and post-processing by the cortex is very different from the process of making and rendering a photograph, video or film.
