The Bresser 10x50 Corvette are a great option for those who want a moderately-priced general-purpose pair of binoculars of decent quality
And which are also perfectly suited for astronomy. Read our full Bresser 10x50 Corvette binoculars review.
Orion is one of the most well-respected names in the binocular world
And their 09466 Mini Giant is one of the better astronomy binoculars they’ve produced. Their Mini Giants work to pull in more light than a 50mm glass
But don’t come with the extra weight that the “giant” models can burden you with.
When choosing a pair of astronomy binoculars
There are two essential specs to pay attention to:
Total magnification power and the lens diameter. Magnification controls how wide or narrow your viewing experience will be—a lower magnification indicates a wider field of view
While a higher magnification offers a more narrow but focused view.
A FOV of around 325 feet per 1
000 yards is recommended for an optimum viewing experience. Prism – Binoculars use a prism to manipulate light and increase magnification power. Most binoculars use a Porro prism
Which is the best at offering crisp views.
Weight is the last major component of astronomy binoculars. Some binoculars made for stargazing have huge objective lenses that can cause your binoculars to weigh up to ten pounds. When you are looking up at the stars, this weight will rest right on your eyes, and it can become uncomfortable quickly.
Binoculars come in two body styles: the familiar "stepped" look of the Porro-prism design (right), and the sleeker "H" profile of the roof-prism design (below right). Most binoculars marketed for astronomy use Porro prisms, named for the Italian optician who invented them in the 1850s.
The Gosky 4332111342 Titan Astronomy Binoculars are our pick for the best overall. These binoculars feature large 80-mm objective lenses that let in plenty of light for a bright, clear image with plenty of contrast. The 20X zoom is strong enough to see craters on the moon as well as the moons of Jupiter.
Pair of telescopes mounted side-by-side
Binoculars or field glasses are two refracting telescopes mounted side-by-side and aligned to point in the same direction
Allowing the viewer to use both eyes when viewing distant objects.Most binoculars are sized to be held using both hands
Although sizes vary widely from opera glasses to large pedestal-mounted military models.
In astronomy, angular separation between the Sun and a planet, with the Earth as a reference point
A planet's elongation is the angular separation between the Sun and the planet
With Earth as the reference point.The greatest elongation of a given inferior planet occurs when this planet's position
In its orbital path around the Sun
Is at tangent to the observer on Earth.Since an inferior planet is well within the area of Earth's orbit around the Sun
Observation of its elongation should not pose that much a challenge.When a planet is at its greatest elongation
It appears farthest from the Sun as viewed from Earth
So its apparition is also best at that point.
Study of the Milky Way galaxy and its contents
Galactic astronomy is the study of the Milky Way galaxy and all its contents.This is in contrast to extragalactic astronomy
Which is the study of everything outside our galaxy
