What telescope focal length is best for astrophotography?

For reference, wide-field astrophotography setups generally stay at or below 70 mm focal length. Any longer and you’ll start finding some objects difficult to catch in one frame. The focal length also influences another major factor in all of this, which is the focal ratio.

How do I choose a telescope for astrophotography?

The best type of telescope for astrophotography will vary greatly depending on the type of imaging you want to do. If you want to image the planets and have fine resolution on the moon, you will want a telescope with a large aperture and long focal length.

Can a Dobsonian telescope be used for astrophotography? Generally, we do NOT recommend doing astrophotography with your Dobsonian telescope, as the lack of a tracking mount or an equatorial mount will make long exposures impossible. That being said, photographs of the Moon, planets, and very short exposures of bright nebulae are doable with the right expectations.

What was Galileo’s telescope? Galilean telescope, instrument for viewing distant objects, named after the great Italian scientist Galileo Galilei (1564–1642), who first constructed one in 1609. With it, he discovered Jupiter’s four largest satellites, spots on the Sun, phases of Venus, and hills and valleys on the Moon.

What can you see with a 500mm telescope?

A 500mm telescope will yield a lunar image that’s about 5mm across in a DSLR camera with a full-frame, 35mm-format sensor; a 1,500mm telescope will produce a 14mm image, and a 2,000mm telescope results in an 18mm image.

Why are refractors better for astrophotography? If you are interested in astrophotography, purchasing a refractor is a better option because of it’s specialized optic design that captures deep space objects like galaxies and nebulae. If you are interested in brighter celestial objects like the Moon or planets or a beginner, a reflector telescope is ideal.

What is an equatorial telescope mount?

An equatorial mount is a mount for instruments that compensates for Earth’s rotation by having one rotational axis, the polar axis, parallel to the Earth’s axis of rotation. This type of mount is used for astronomical telescopes and cameras.

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.

What can I see with a 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. Mars, Venus and Mercury are visible in a small scope as well, but are extremely reluctant to give up any detail because of their overwhelming brightness.

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;

How did Galileo telescope work? In Galileo’s version, light entering the far end (1) passed through a convex lens (2), which bent the light rays until they came into focus at the focal point (f). The eyepiece (3) then spread out (magnified) the light so that it covered a large portion the viewer’s retina and thus made the image appear larger.

What is Galileo telescope made out of?

Original telescope made by Galileo consisting of a main tube and two smaller housings in which the objective and the eyepiece are mounted. The main tube consists of two semicircular tubes held together with copper wire. It is covered with paper.

What did Galileo’s telescope look like? Galileo’s Telescopes

It had a convex objective lens and a concave eyepiece in a long tube. The main problem with his telescopes was their very narrow field of view, typically about half the width of the Moon. The earliest known sketch of a telescope, August 1609.

What can you see with a 90mm 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.

Is a Newtonian telescope good for astrophotography? The Perfect Astrophotography Telescope

For example, a Newtonian Reflector presents an advantageous light-gathering ability and an affordable price-per-aperture. However, Newtonians require regular collimation and adjustments to avoid coma and perform at their best.

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 [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.

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.

Do you need an equatorial mount for astrophotography?

To do serious long-exposure astrophotography, you are going to need a good German equatorial mount that has gears and motors in both axes, and altitude and azimuth adjustments for precise polar alignment. You will also need a solid tripod or pier.

What is a Dobsonian mount? A Dobsonian telescope is an altazimuth-mounted Newtonian telescope design popularized by John Dobson in 1965 and credited with vastly increasing the size of telescopes available to amateur astronomers.

What is the difference between the alt azimuth and equatorial mounts?

Alt-azimuth mounts track in iterative up/down – left/right movements. Equatorial mounts are essentially alt-azimuth mounts but tilted at an angle based on your GPS longitude. This also corresponds to the altitude at which the north star (Polaris) sits in your sky.
