Best Binoculars For Stargazing And Astronomy

It is often said that binoculars are the best “first telescopes”. They really are simply two small telescopes side by side, with a little extra optics magic to make the eyepieces close enough so you can comfortably look through both scopes at the same time. Binoculars are easy and intuitive to us, unlike larger telescope that can be overly complicated and frustrating for beginners, were as binoculars produce a rightside-up image and provide a large viewing field which make it easy to locate objects in the night sky, it also requires no aligning, you can simply grab your favourite pair, head outside and point them to the stars. Binoculars are especially useful for seeing large craters on the Moon, the moons of Jupiter, then if you’re lucky enough the occasional comet! You find more often than not it will be a pair of binoculars that you will grabbing first to scope out the night before grabbing your trusty telescope.

We compiled a list of the best binoculars for stargazing Astronomy.

Celestron SkyMaster 25X100 ASTRO 

Celestron SkyMaster 25X100 ASTRO

The Skymaster range of binoculars are one of the most highly regarded astronomy binoculars available on the market, they offer a unique optical design that makes for an exceptionally flat field of view, which translates amazingly well to low light situations and making it an excellent choice for astronomy as the field of view is expansive and image quality crisp and clear resulting in excellent performance at a great price.

The larger SkyMaster models (100mm) have been designed by Celestron to meet the unique demands of longer terrestrial viewing sessions, including features such an enhanced structural reinforcement to the main body of the binoculars making them a very durable piece of equipment, a built in  tripod adapter to enable easy attachment to tripods and other fixing devices, the SkyMaster model features high quality BAK-4 glass on their porro prisms and multi-coated optics giving an enhanced bright contrast at low light setting .

Celestron did an amazing job keeping stargazers in mind when designing the SkyMaster 25×100. The caters of the moon, jupiter and its four moons, along with Saturn’s rings are all viewable with the 25×100 giving you a spectacular and unique peek at the universe in very portable and egomaniac way.

Bushnell Falcon 10×50

Bushnell Falcon 10x50

At a unbeatable price and compact design the Bushnell 10×50 are a great choice for users not wanting to break the bank, a versatile pair of bins, that are ideal for being used on the go, from stadium sports, bird watching and of course giving the powerful magnification there are well suited for astronomy, the porro prism coated lens give good sharp feedback and you can not be disappointed with the optics at the price point of these, another nice feature is the clever fold-down eye cups the protects glasses from getting scratched.

Giving the low price point, there a few draw backs mainly the question of durability,  having dropped these once or twice they do scratch up quite easily, although the optics are very good for the price and are more then sufficient especially for getting you into astronomy, they don’t quite have the same optics as more premium models, but then again those models also cost twice, four and five times the amount of the Bushnell.

Swarovski EL 10×50
Swarovski EL 10×50

NO binocular review would be complete without the granddaddy of them all at whopping $2k these are one pricey pair for bins,  are they best yes, are the best value no, I personally wouldn’t buy these as I would just rather spend it on a good telescope but these are on the list as they are exceptional and if you got the cash why the hell not!

If you ever held a pair of good binoculars you’ll notice how bulky and heavy they really are, ergonomics are not the strongest suit in the binoculars world, but the Swarovski’s entry is a bit different with ergonomics in mind the Swarovski just feels right not to bulky and not too heavy combine this with the renowned quality of Swarovski’s image capabilities  giving bright and sharp images almost right to the edge of the field; and a field of view that is steady and expansive, even the close focus distance is also superb for a 12X (~3m), and the focus knob moves smoothly and quickly between objects very close and those much more at a distant, making these one most exceptional pair of bins on the market today for astro viewing.

Even after extended use in the field, I experienced no eye fatigue looking through these binocular, which is a god send as lately eye fatigue has been a huge torn in my side, there was also no obvious chromatic aberration or distortion; the view appeared as balanced and flat as you’d expect although I did notice that it exhibits same greenish and yellowish tint (a common feature of Swarovski, some prefer others don’t)

The binoculars are one of the most eyeglass-friendly binoculars available, personally I do not wear glasses but most of my colleagues do and we all agreed that eye relief was ample, and the eyecup design was among the best of any of the binoculars we’ve tested.

The drawbacks there aren’t many although for me personally they feel much lighter than other pairs I’ve tested after a long night you may start feeling the effects of the weight and of course the other down side is the price these are one of the most expensive pair on the market today, But they are an unquestionably solid product.

Orion 9326 Giant View 25×100 Astronomy Binoculars
Orion Gaint View 25×100 Astronomy

The biggest and brightest astro-binocular from Orionm featuring 100mm objective lenses and strong 25x magnification, Fully multi-coated optics, high quality BAK-4 prisms and internal baffling ensure sharp images and pleasing contrast with maximum light throughput, the barrels are cross-reinforced for maximum structural rigidity and an  unflinching optical alignment, Long 18mm eye relief lets eyeglass wearers see an unrestricted field of view without removing their corrective lenses, Jupiter’s satellites are also well resolved and the Moon details you’ll get to see are simply amazing with the Orion.

On the down side the Orio’sn Weigh in at 10.1 lbs for which a tripod is recommended for comfortable viewing, there is some chromatic aberration and comma towards the outer field of view little disappointing given the price point and are not waterproof, which although not many stargazer are out in the pouring rain, but at the price would have a nice to have.

About Refracting Telescope

A refractor telescope, also known as a refracting telescope, is a type of telescope that uses a lens to focus light. It was one of the first types of telescopes invented and is still used by astronomers today. The lens at the front of the telescope is called the objective lens, and it is responsible for gathering light and bending it so that it converges to a point of focus at the back of the telescope, where an eyepiece is located to magnify the image formed by the objective lens.

The Optical Design

The optical design of a refractor telescope is relatively simple. The objective lens is a convex lens, meaning that it is thicker in the middle than at the edges. When light passes through the lens, it is refracted, or bent, by an amount that depends on the angle at which it hits the lens and the properties of the glass. The refracted light converges at a point called the focus, which is located a certain distance behind the lens. The distance between the lens and the focus is called the focal length, and it is an important characteristic of the objective lens.

The eyepiece is a small lens that is placed near the focus of the objective lens. Its job is to magnify the image formed by the objective lens so that it can be viewed by the observer. The magnification of the telescope is determined by the ratio of the focal lengths of the objective lens and the eyepiece. For example, if the focal length of the objective lens is 1000mm and the focal length of the eyepiece is 10mm, the magnification of the telescope would be 100x (1000/10 = 100).

In addition to the objective lens and eyepiece, refractor telescopes typically have a few other components to help with focusing and alignment. A diagonal mirror is often used to redirect the light from the objective lens to a more comfortable viewing angle. A focuser is used to move the eyepiece closer or farther away from the objective lens to achieve a sharp focus. Finally, a mount is used to support the telescope and allow it to be pointed at different objects in the sky.

The Advantages of Refracting Telescope

One advantage of refractor telescopes is that they produce high-quality images with good contrast and minimal chromatic aberration. Chromatic aberration is a phenomenon where different colors of light are refracted differently by the lens, causing a rainbow-like effect around bright objects in the image. This can be a problem with some types of lenses, but it is less of an issue with refractor telescopes because they use a single lens to focus the light.

Another advantage of refractor telescopes is that they are relatively low-maintenance. Because the objective lens is sealed inside the telescope tube, it is protected from dust and other debris. This means that the lens does not need to be cleaned as often as the mirrors in a reflecting telescope. However, it is still important to keep the lens clean and free of fingerprints or other smudges, which can degrade the image quality.

Overall, a refractor telescope is a simple but powerful tool for observing the night sky. With a well-made objective lens and a high-quality eyepiece, it is possible to see many of the wonders of the universe, from the craters of the Moon to the rings of Saturn and beyond. Whether you are a seasoned astronomer or a curious beginner, a refractor telescope is a great way to explore the cosmos and deepen your appreciation for the beauty and complexity of our universe.
