Choosing the Most Powerful Binoculars for Astronomy
In order to get the best high powered binoculars for astronomy, here are some of the important factors to put into consideration:
Magnification power-Magnification is often given the first priority by people shopping for astronomy binoculars. Having a high magnification isn’t always going to make a huge difference because a 10x magnification will be enough to take a look at the moon and see the star cluster close to you.
However, if your goal is to look at long distant terrestrial objects such as planets, a higher magnification power such as 20x will be ideal for you. Normally, magnification power is represented in the first binocular specifications. For instance, in 15×70, the 15x means that the binoculars have 15x magnification.
Eye relief-Eye relief refers to the optimal distance from the eyepiece to your eye. An adequate eye is an important factor to be taken into consideration especially if you put on glasses.
If you wear glasses, look for eye relief of at least 11mm. Certain binoculars feature diopter adjustments that allow eye-glass-free viewing. Other binoculars feature collapsible eyecups to accommodate users who put on glasses.
Size and weight-Regardless of how powerful they might be, full-sized binoculars for astronomy can sometimes weigh up to at least 2 pounds. The type and amount of glass used in the construction process also affect the final weight of the unit.
Since viewing terrestrial bodies might require you to move from one point to the other, it is recommended to carry lightweight binoculars which are easy to carry when moving from one point to the other.
With large-sized binoculars having more merits such as having better image quality and higher magnification, they might be heavy to hold for long hours of viewing. This will necessitate the use of a tripod for comfortable viewing as well as enjoying long hours of viewing.
Armoring and coatings-Binoculars lens coating improves the performance of its lens by minimizing reflections and maximizing contrast. The coating on both lenses and prisms enhances light transmission. In addition, marine-specific binoculars feature hydrophobic coatings that help bead and remove water spray on the optics.
Armoring is done to protect the binoculars from getting damaged in case they fall on hard surfaces. Rubber armoring also provides a secure and firm grip on the user’s hands.
Objective lens size and aperture-The The aperture of any binoculars directly affect how much light comes in. astronomy is done in the dark, therefore you will require a really big aperture.
This ensures that more light gets through giving you bright images full of detail and contrast. The same applies when it comes to the size and quality of the objective lens. Stars and faint celestial objects are seen against a dark sky are much more demanding, therefore mediocre optics will display their flaws.
Large diameter lenses usually measured in mm result in better image quality. Typically, the size of the objective lens is found on the second number of a binocular specification.
Exit pupil-The exit pupil in a binocular affects how much light comes out of it. All of the focused light is usually concentrated into a small circular image, which is later taken in by your eye through the eyepiece.
The ideal exit pupil should range between 5-9mm in diameter. If the exit pupil is smaller, it can result in a darker image.
