There are many ways a person can indulge their stargazing hobby, but one of the most effective devices to help people in this field is a single telescope.  Monoculars bring distant objects close to your eye, allowing you to view them easily.  It allows a sufficient amount of light to enter the lens and produce a bright image.  Its small, portable, compact, and efficient equipment is far better than carrying a heavy telescope on a field trip or camping trip.  

The market is flooded with monocular devices of all sizes, and choosing the perfect device for a newcomer to the field is no easy task.  This buying guide will help you buy the best stargazing monoculars.  

How to buy the best stargazing monoculars

1. Eye relief  

Eye distance is the distance between the lens and the eye, usually between 10 and 20 mm.  When looking for the best monoculars, you might not think eye relief is an important feature.  There are, however, at least two reasons to consider.  Ocular relief has a great impact on the comfort of one eye.  If the lens is too close or too far away, the image quality can also be affected.  If you wear glasses, it’s important to look for an eye distance of 15 mm or more.  

2. Lens coating  

Monoculars come with one of three different types of lens coatings.  

Simple lens coatings are the most affordable, however, most enthusiasts are looking for fully coated lenses.  

Fully coated lenses help reduce glare while improving the brightness and sharpness of images.  

Multilayer coated lenses are the high-end spectrum of coating technology used to make the best single telescope.  They offer top-notch picture quality, but also at a high price.  A good coating not only increases visibility but also removes water and fog.  

3. The aperture  

In the 7×50 case, the single barrel has an aperture of 50mm.  Aperture is the diameter of the objective lens.  This is the first lens that which light enters the monoculars.  It affects overall brightness and clarity.  The larger lens diameter will allow light to pour into the single barrel and create crystal-clear images.  

4. View

The human eye usually has a field of vision of about 180 degrees.  Thanks to our peripheral vision, we can see whatever we are looking at.  Unfortunately, you can’t get the same results when viewing through an optical device.  

The greater the magnification of a single telescope, the lower the field of view.  This may affect your ability to see the stars up close.  The wider view will allow you to see more of the night sky at once.

5. The pocket  

The word monocular explains itself because if you split the word into two parts, it loses its meaning.  It is roughly translated as a monocular optical device.  Monoculars are smaller, more compact versions of telescopes.  

The main benefit of having a single telescope is its portability, as it’s easier to hold in your hand and stable, so it doesn’t need a lot of accessories such as tripods and stands, which can save a lot of money.  Some monocular devices can even be folded down to smaller than their original size to become pocket-sized objects.  

6. Night vision  

Monoculars need light to produce images.  Sometimes the light from the target star system is not enough.  Fortunately, many monoculars compensate for this with night vision.  

Night vision technology uses light reflected from the sun.  It amplifies any available light.  This is good for the focal plane and creates bright images.  

Even if you’re looking up at the stars, night vision technology can greatly improve visibility.  

7. Focus systems  

No one’s eyes are alike.  The excellent focus system ensures that everyone with a single telescope can make adjustments to suit their eyes.  Note the one-handed focus knob.  You can also get units with a diopter eye mask for greater accuracy.  These models are perfect for people who wear glasses.  

If your desire is only to study the stars and you can use your equipment for other purposes, such as wildlife viewing, then you are better off with a single telescope.  This compressed telescope-like device is the perfect companion for a trip to a mountain station free of pollution and artificial light, where the night sky opens up to reveal its starry secrets.  Finally, most optical devices are not waterproof, but some monocular models do offer this specification, so if you are the adventurous type, please always prefer a waterproof device.
