What is a Monocular and Why Buy One?
Many people think that you need an enormous telescope to go stargazing. While they certainly help, monoculars do a fantastic job, too.
To put things simply, monoculars are basically miniaturized refracting telescopes. They are optical devices that use a series of lenses to magnify the image.
The easiest way to look at these devices is to think of them as one half of a pair of binoculars. Monoculars feature a lot of the same technology as binoculars. But, they only feature one objective lens and eyepiece!
Monocular telescopes have a lot to offer. However, their biggest draw is portability. These devices are compact and made for outdoor use. That’s a stark contrast to traditional telescopes, which usually have enormous optical tube assemblies and clunky tripods.
Most monoculars are small enough to wear around your neck, stuff in a pocket, or stash in a backpack. Not only that, but you can use them with one hand. Quickly whip the monocular out when you see a clearing to get a view of the stars. There are no complicated setup or major requirements to get a clear view.
The magnification power you get isn’t going to be the same as a telescope. That said, monoculars still offer plenty of power to appreciate the cosmos. There’s a lot of optical gear inside these handheld viewing devices!
Best Monoculars For Stargazing Buying Guide
Monoculars come in a wide range of designs and specifications. There are tons of options on the market for you to choose from. Just take one look through Amazon and you’re bound to find hundreds. If you’re not familiar with spec sheets and technical jargon, picking up the right one is easier said than done.
Whether you’re a seasoned astronomer or a hobbyist looking to invest in their first monocular, use the following factors to zero-in on the perfect device for you.
With large telescopes, light is passing through several glass lenses and mirrors before it makes it to your eye. The same goes for monoculars. But, a different type of technology is used to keep these devices as compact as possible. Manufacturers utilize prisms.
There are two main types of prism designs used in monoculars. Both work alongside the objective lens and eyepiece to magnify the image. However, they offer different results.
The first is a roof prism. If you were to cut the monocular in half and take a look at the prisms, they’d look like nothing more than a couple of pieces of cut glass. But in reality, roof prisms are fine-tuned optical devices with great precision.
The prisms are uniquely shaped to bounce light strategically. As light enters the monocular, it reflects off of multiple sides of the prism before hitting the eyepiece. The result is a more direct path and compact shape.
Roof prisms tend to be more expensive than the alternative. But, manufacturers are able to stuff the prism into a much smaller monocular body. So, the final product is usually more streamlined and compact in terms of design.
With a Porro prism, light bounces in a more uniform zigzag pattern. Like roof prisms, Porros look rather simple at face value. Yet, they’re precision cut to provide the best light path possible.
Because the path is more controlled, Porro prism monoculars often provide great optics. The image is slightly clearer than the one you’d get on a roof prism. Not only that, but the final image has a better field of view and provides better depth perception.
The downside of a Porro prism monocular? It’s all about the size! Porro prisms are clunkier, which affects the overall shape of the device.
Focal Length and Magnification Power
Whether your monocular telescope has a Porro prism or a roof prism, there are other specifications to consider. One of the most important is magnification power.
When you shop for monoculars, you’ll likely see two numbers somewhere in the description. Those numbers aren’t just random. They’re optical descriptors that provide you with more information about the monocular’s capabilities at a glance. For example, you might see a product labeled as 7×50.
The first number refers to the magnification power. In the example above, the monocular would provide 7X magnification! That’s easy enough to understand, but what does this have to do with the focal length?
Well, the focal length directly impacts magnification capabilities. The focal length refers to the distance between the outermost lens, the objective lens, and the focal plane. The focal plane is where the light converges to create the image.
A longer focal length will result in more magnification! Of course, monoculars are all about portability, so don’t expect to get a lengthy device with an ultra-high focal length.
The next measurement to consider is aperture. Remember our number descriptor from earlier? Well, the second number reflects the aperture. In the 7×50 example, the monocular has an aperture of 50mm.
The aperture is the diameter of the objective lens. This is the very first lens that the light hits to enter the monocular. It impacts overall brightness and clarity. A wider lens diameter is going to let the light flood into the monocular and create a crystal-clear picture.
Field of View
The human eye usually has about a 180-degree field of view. Thanks to our peripheral vision, we can get a wide view of whatever we’re looking at. Unfortunately, you can’t achieve the same results when looking through an optical device.
The more magnification a monocular has, the lower the field of view. This could impact your ability to get a close-up view of the stars. A wider field of view will let you see more of the night sky at once.
Monocular telescopes are designed to be put through the wringer. But, some models are hardier than others. Think about where you plan on taking your monocular and choose a model that can hold up well to environmental hazards and wear and tear.
Many manufacturers go to great lengths to ensure that their monoculars are as resistant to damage as possible. You might see water-resistant builds, shockproof design, and more. Devices covered in protective rubber armor will hold up much longer than bare-bone units.
Night Vision Capabilities
Monoculars need light to produce an image. Sometimes, the light shining from your target star system is not enough. Luckily, many monocular compensate for this by having night vision.
Night vision technology utilizes light that’s reflected from the sun. It amplifies whatever light is available. This benefits the focal plane and creates a bright image.
Even when you’re looking up at the stars, night vision technology can do a lot to improve visibility.
No one’s eyes are the same. A great focuser system ensures that everyone using the monocular can make adjustments that work for their eyes.
Look out for one-handed focuser knobs. You can also get units with diopter eyecups for greater precision. Those models work great for those with eyeglasses.
A couple of extra performance features here and there can take monoculars to the next level. Many seasoned astronomers utilize monoculars as spotting scopes before focusing a larger telescope.
Units with good low light transmission and a reticle could help with that task.
Many monoculars also come with features focused on daytime use. For example, you might see rangefinders to help you calculate distance while bird-watching.
As you can see, you have a lot of great units to consider! The best monoculars for stargazing are going to have great optics and some handy features to help you make the most out of your time under the stars. Give one of these monoculars a shot and see what kind of galactic wonders you can view.
