What can you see with a 130mm Newtonian telescope?
The Moon looks absolutely amazing at 130mm aperture. You will be able to see pretty much every crater in high levels of detail. Every geological feature is visible. You will definitely want to grab a Moon filter so you can look at it in all its glory.
What is the magnification of a Newtonian telescope?
The telescope had a flat diagonal secondary mirror bouncing the light at a 90° angle to a Plano-convex eyepiece with a probable focal length of 4.5mm yielding his observed 35 times magnification.
Is a Newtonian telescope good?
Newtonian reflectors are great all-around scopes, offering generous apertures at affordable prices. They excel for both planetary and deep-sky viewing. Of course, the larger the aperture, the more you’ll see.
What can you see with 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;
Which is better Newtonian or refractor?
A reflector telescope is said to be the best value for your money, as they offer the most aperture for your dollar. For example, a 6-inch diameter refractor telescope can cost up to 10X as much as a 6-inch Newtonian reflector.
What can you see with a 200mm telescope?
Large aperture telescopes of 10” (200mm) and larger are generally used for viewing what are a called “Deep Sky” objects. These are star clusters, nebulae and galaxies.
What can you see with a 114mm reflector?
Celestron’s Cometron 114mm f/4 Reflector Telescope makes an ideal entry-level instrument that is well-suited for making detailed observations of the Moon and planets, and bright deep-sky objects like star clusters, binary systems, and nebulae.
How big of a telescope do you need to see Pluto?
10 inches
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.
What can you see with a 120mm telescope?
80-90 mm refractors, 100-120 mm reflectors, 90-125 mm catadioptric telescopes:
- binary stars with angular separation of over 1.5″, faint stars (up to 12 stellar magnitude);
- structure of sunspots, granulation and solar flares (with an aperture filter);
- phases of Mercury;
- lunar craters (5 km in diameter);
Is a 150mm telescope good?
150mm Newtonians are great all-rounders. The short focal length ones (f4 = 600mm focal length to f6 900mm focal length) are especially good for ‘deep sky’ (Galaxies, Nebulae, Star Clusters). Focal ratios of f6 to f8 are good for planetary views too! Newtonians over f8 (1200mm/150mm) are very cumbersome.
