You can view Earth’s Moon, the Sun (with proper filter), the Moons of Jupiter, many open star clusters, the Orion Nebula, and Andromeda Galaxy. Note that these are mostly large objects which do not require a great deal of magnification, which a 70mm telescope with 300mm focal length cannot provide.
What is a good focal length for a telescope?
around 1000mm to 1200mm
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.
What can you see with a 30mm telescope?
Bring land and sky objects 30 times closer; and view large astronomical features like bright lunar craters. Simple, yet robust, this compact telescope is the ideal introduction to the wonderous world of astronomy. Can be used as a hand-held ‘spy glass’ as well as supported in the small, metal tripod.
Can I see the rings of Saturn with a 70mm telescope?
You can’t compress all those light years of distance with an eyepiece. 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 is a good magnification for a telescope to see planets?
Experienced planetary observers use 20x to 30x per inch of aperture to see the most planetary detail. Double-star observers go higher, up to 50x per inch (which corresponds to a ½-mm exit pupil). Beyond this, telescope magnification power and eye limitations degrade the view.
What can you see with a 90mm refractor telescope?
A 90mm telescope will provide you with a clear view of the Saturn along with its rings, Uranus, Neptune, and Jupiter with its Great Red Spot. You can also expect to see stars with 12 stellar magnitude with a 90mm telescope.
What telescope is best for viewing galaxies?
Best telescopes for viewing galaxies
- Orion SpaceProbe 130ST.
- Solomark 114AZ.
- Orion SkyView Pro 8.
What can I see with a 700mm 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. Mars will look great.
How big of a telescope do I need to see Pluto?
eleven inches
Observing Pluto is the ultimate challenge. It is smaller than Earth’s moon and is approximately 3.3 billion miles away from us. You will need a large aperture telescope of at least eleven inches.
What size telescope do I need to see the rings of Saturn?
25x
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 with a 100mm telescope?
What Can You Expect From 100mm Telescopes? (With Photos)
- The maximum magnitude of a 100mm telescope is 13.6. For reference, the Moon has a magnitude of -12.74 and Mars has a magnitude of -2.6.
- The Moon. The Moon looks amazing in these telescopes.
- Mars.
- Venus.
- Jupiter.
- Saturn and Neptune.
- Pluto and Dwarf Planets.
- Mercury.
What can I see with a 130mm reflector telescope?
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 magnification do you need to see Mars?
In general, the best magnification for viewing Mars is 35x per inch of aperture when using a telescope of up to about 7″, and roughly 25x to 30x per inch of aperture for larger telescopes.
How big of a telescope do you need to see Jupiter?
A well-made 5-inch refractor or 6-inch reflector on a sturdy tracking mount is really about the minimum for serious Jupiter observing. Larger instruments will allow scrutiny of fine detail and subtle low-contrast markings.
What can you see with a 20x telescope?
A small Jupiter with its moons, the Moon as a whole, not so much on the detailed features, a very faint M31 galaxy, the Orion Nebula, some whisps of nebulae in and around Sagittarius, 47 Tuc, the LMC and SMC… in other words the big and bright obvious stuff you can pick out with your naked eyes.
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.
What can I see with a 80mm telescope?
The 80mm objective lens and short 400mm (f/5.0) focal length are perfect for taking in wide swaths of the heavens, making it ideal for larger deep-sky objects. You’ll see spectacular star clusters, wispy nebulas, and expansive galaxies with this telescope, but it also excels at viewing objects in our solar system.
Is a 90mm refractor good?
The Orion Astroview 90mm refractor is an ideal telescope for novice astronomers ready to invest in their first model. There are some shortcomings, but this affordable telescope offers the laser-sharp optics that refractors are known for and is ideal for your first views of the Moon, planets, and stars.
What can I see with a 150mm telescope?
150-180 mm refractors, 175-200 mm reflectors and catadioptric telescopes:
- binary stars with angular separation of less than 1″, faint stars (up to 14 stellar magnitude);
- lunar features (2 km in diameter);
- Clouds and dust storms on Mars;
- 6-7 moons of Saturn, planetary disk of Titan may be observed;
What is the most powerful telescope for home use?
Here are a few of the best models available:
- Celestron CGX-L Equatorial 1400 Telescope Bundle.
- Celestron CGX-L Equatorial 1400 EdgeHD Telescope Bundle.
- Meade LX200 14-inch Telescope Bundle.
- Celestron 14-inch OTA.
- Celestron 14-inch EdgeHD OTA.
- Meade LX850 16-inch f/8 OTA.
- 40-inch: Planewave 1 Meter Observatory Telescope.
Is Meade better than Celestron?
Meade and Celestron are both top brands in the telescope business. It does not seem Meade is any better or worse than Celestron as both make great products that can last a life time with proper care and use. However, Meade’s prices are much higher compared to Celestron, which may help you decide what brand to go for.
